Team officials on Friday unveiled a new logo with the number 10 including the Titans' fireball, the silhouette of Tennessee and the years 1999-2008. The Titans will wear the logo as a patch on the left, front shoulder of their jerseys this season as well.

Owner Bud Adams said in a statement he looks forward to the fun of looking back at the moments and players defining the franchise over the past nine seasons. He remembers deciding to start from scratch and select a new nickname and uniform to go with the new stadium being built in Nashville along with a new headquarters for his team.

"I would love to finish the decade as we started it -- in the Super Bowl," Adams said.

The logo will be on merchandise for fans to buy, of course, and will be on display at LP Field during the 2008 season. The team has also lined up past players like kicker Al Del Greco and receiver Kevin Dyson to take part in an offseason tour across Tennessee and into parts of Alabama and Kentucky that begins April 14.

The Titans are asking fans to help select the favorite players, games and moments over the past nine seasons in voting on the team's Web site.

Taking time to celebrate seems only right for a franchise that endured a difficult relocation from Houston before severing ties with Texas by dropping the Oilers' nickname for a new name fresh for fans in the team's new home.

Steve Underwood, the team's senior executive vice president, said he sees the team's relocation as the most tumultuous in the history of professional sports considering the litigation the Oilers faced in Houston, a referendum in Nashville on whether to build the stadium and Congress attempting to intervene in the move.

The players, coaches and staff also had to deal with a move in July 1997 just before training camp, followed by a difficult season spent commuting to Memphis where the then-Oilers played in front of few fans, the same fans who continued to stay away in 1998 when the team moved to Vanderbilt Stadium in Nashville.

But everything clicked in 1999 with the new nickname, uniform and opening of the new stadium, now called LP Field. The Titans went 13-3 and reached the lone Super Bowl, where they lost to St. Louis, the first of five playoff berths in the past nine seasons.

The team also has sold out each of the 93 games played there, with every suite full and every spot of signage sold.

"If you had been through what we went through to get here and have had the kind of support we've had from our fans, it's made it all worthwhile," Underwood said.

“Jake is an intelligent and fundamentally sound player,” said Titans General Manager Mike Reinfeldt. “He is a technician at the position who rarely makes mistakes, and he has enough versatility to play either guard spot.”

In four seasons with the Colts, Scott (6-5, 295) played in 60 total games with 57 starts, including a current streak of 55 consecutive starts.  All but four of his starts came at right guard.  He also filled in at right tackle (three starts) and left guard (one start). 

Additionally, Scott has eight career playoff starts, all at right guard, including every game during the Colts’ run to a Super Bowl XLI Championship at the conclusion of the 2006 season.

The Titans picked Herndon up from Seattle last June and agreed to a three-year deal with the veteran as they tried to shore up their secondary. That came after the season-long suspension of cornerback Adam "Pacman" Jones.

But Herndon, who played in 73 regular-season games with Denver and Seattle with 49 starts, wound up being an expensive insurance policy in Tennessee.

He played in only four games and had just two tackles as second-year cornerback Cortland Finnegan won the starting job left empty by Jones' suspension.

The 26-year-old Hadnot is a four-year veteran who has started 55 of 63 games with the Miami Dolphins. The Titans are looking at experienced linemen after losing starting left guard Jacob Scott in free agency to St. Louis.

His body had other plans.

McNair announced his retirement Thursday, ending a 13-year career in which he was selected co-MVP, led the Tennessee Titans to the Super Bowl and orchestrated the most successful regular season in the Ravens history. He received a standing ovation from his teammates after revealing his decision, then contained his emotions during a hastily arranged news conference.

"Coming out and making this decision, it was hard," he said. "In your mind, you feel like you can play, that you can still compete. But when your mind and your body are not in accord, it's not going to work in the National Football League.

"My mind was there. Mentally, I could go out and play. But physically, I couldn't do it anymore. Not to the capacity that I need to help my teammates win a football game."

The 35-year-old McNair guided the Ravens to a franchise-best 13-3 record in 2006, his first season in Baltimore. But he injured his groin during the season opener last season and never regained the form that enabled him to earn a berth in four Pro Bowls.

McNair developed back and shoulder injuries and played in only six games in 2007. He threw only two touchdown passes, was intercepted four times and lost seven fumbles before being placed on injured reserve in December, ending his most frustrating season in the NFL.

He underwent surgery on his non-throwing shoulder in December and spent much of the past three months getting ready for his 14th NFL season. But McNair had an inkling that all the running and weightlifting might be for naught.

"My mind was telling me, 'Yes,' and my body was like, 'No, what are you doing?' I came up with (the idea of retiring) two or three days ago, but it's been lingering ever since December."

The news stunned his teammates, who expected McNair to return — if only to prove last season was fluke.

"I thought I was going to get at least one more year, because I know Steve has a big chip on his shoulder," said receiver Derrick Mason, who also played with McNair on the Titans.

Brad Hopkins, who protected McNair's blind side at left tackle with the Titans, said, "Sure, he had a multitude of injuries and what not. Some way, he always found his way back to the field. For Steve to retire, it's a big deal. You don't usually see that caliber of player come through the NFL on a daily basis."

The highlight of McNair's career might be a five-game stretch at the end of the 2002 season in which the quarterback was banged up so much he could not practice. Yet, he started all five games and led the Titans to wins to finish 11-5 and reach the AFC championship game for the second time in four seasons.

"If you don't take those things into consideration when talking about Steve and the accomplishments he made, you're missing the point of the whole thing," Hopkins said. "He did it, and he's always done it as a competitor. He's one of those guys you want your young quarterbacks to be like him as far as the toughness."

The Ravens now have two quarterbacks: Kyle Boller and Troy Smith. First-year coach John Harbaugh said there would be an open competition for the starting job, and general manager Ozzie Newsome insisted the loss of McNair would have "no impact" on the team's direction in the NFL draft later this month.

McNair began his career in 1995 with the Houston Oilers, who eventually became the Tennessee Titans. He led the team to four playoff appearances, including the Super Bowl after the 1999 season. He was chosen co-MVP of the league in 2003, sharing the award with Peyton Manning, after throwing for 3,215 yards and 24 touchdowns with only seven interceptions.

McNair fought injuries during the latter part of his career with Tennessee and was dealt to the Ravens in June 2006 for a fourth-round draft pick. He had every intention of completing the five-year contract he signed with Baltimore, but those old wounds finally caught up to him.

"Over 13 years, I had a lot of injuries because I played the game physical, because I gave 110 percent every game," McNair said.

Eddie George, who played running back behind George in Houston and Tennessee, said, "You name the injury and Steve had it and he still showed up. Not only did he show up, but he showed up and played extremely well. For most of his days in Tennessee he played like that. In his MVP year he played most of the year hurt. It is a testament to his willingness to win and how he sacrificed his body for the team."

Tennessee's Jeff Fisher, his coach for most of his career, echoed George's comments, noting that McNair never wanted anyone to know how badly he was hurt.

"Steve was the face of this franchise when we arrived here. And I think in a lot of ways will always be one of the faces of this franchise," Fisher said.

In his first season with Baltimore, McNair played in all 16 games and finished the season with an invitation to play in his fourth Pro Bowl. He threw for 3,050 yards and 16 touchdowns, but was intercepted twice in the Ravens' 15-6 playoff loss to Indianapolis.

Last year, however, was a disaster. After McNair got off to a horrid start, then-coach Brian Billick held the quarterback out for two consecutive weeks before an Oct. 28 bye, hoping the rest would enable the veteran to heal. But McNair was ineffective upon his return: He lost two fumbles and threw an interception in a 38-7 defeat at Pittsburgh, then threw for only 128 yards before being replaced in the fourth quarter of a 21-7 loss to Cincinnati.

It turned out to be the last game of his career.

"It's been a great ride," he said. "It's a sad, emotional day for me. I'm trying to do the best I can to hold it in. But at the same time, I'm opening up a lot more doors for the future. I can become now the father I need to be to my kids."

Linebacker Ray Lewis, who had many memorable duels with McNair before the two became teammates, said, "There is no greater warrior or player with a bigger heart than Steve McNair. "He came into this game and gave it everything he had. He now can walk away with his head held high."

In three NFL seasons, Carr has played in 48 games with four starts.

“Dwyane is a veteran guy who gives us a big body and extensive playing experience for that position group,” said Titans General Manager Mike Reinfeldt.

Blakley, 28, joins the Titans after spending four seasons in Atlanta, where he totaled 59 career games and nine starts.  His career statistics include 21 receptions for 189 yards and one touchdown.

In 2007, the 6-foot-4, 257-pound tight end played in 12 games and recorded a career-high seven receptions for 48 yards.

This is Blakley’s second stint with the Titans, although he has never appeared on the team’s 53-man roster.  He spent the final four weeks of the 2003 regular season and two weeks during the ensuing postseason on Tennessee’s practice squad.  He was with the club through the following training camp but was waived on September 5, 2004.  The Falcons claimed him off waivers the following day. 

Blakley originally was signed by the Kansas City Chiefs as a rookie free agent in 2002.  He spent the majority of the 2002 season with the Chiefs on their practice squad.  In 2003, he played for the Rhein Fire in NFL Europe and spent time on the practice squads of the San Diego Chargers and Miami Dolphins before landing with the Titans.

A native of St. Joseph, Mo., Blakley spent four years at the University of Missouri, where in 43 games he totaled 79 receptions for 868 yards and 12 touchdowns. 

Blakley is the second former Falcons tight end to join the Titans this offseason.  He joins Alge Crumpler, who agreed to terms with the team on March 3.
