Titans' Johnson runs away with it

That blur speeding away from opposing defenses and running off with The Associated Press 2009 NFL Offensive Player of the Year award is Chris Johnson.

Considered the fastest man in pro football, Johnson was uncatchable in setting a league mark for yards from scrimmage (2,509) and becoming the sixth player with a 2,000-yard rushing season.

He is the first NFL player to finish with at least 2,000 yards rushing and 500 receiving (503).

That earned the second-year pro 381/2 votes Wednesday from a nationwide panel of 50 sports writers and broadcasters who cover the NFL. Johnson easily beat New Orleans quarterback Drew Brees, who received 9 votes.

"I kind of realize what I did and I feel like I had a dream season," said Johnson, who scored 16 touchdowns (14 rushing), second to Minnesota's Adrian Peterson, and tied the NFL mark with six consecutive games rushing for at least 125 yards.

Johnson, who has run a 4.2 40 and believes he will remain the NFL's fastest player unless a team signs Usain Bolt, has bigger dreams, too: breaking Eric Dickerson's single-season rushing record of 2,105 yards, and winning the league MVP award.

"I didn't even get 1 vote at all (for MVP)," Johnson said. "Like the season I had, it seemed like, 'What more do they want me to do?' That just felt like rookie of the year; it's a quarterback thing I guess."

Atlanta QB Matt Ryan beat out Johnson for 2008 Offensive Rookie of the Year.

Retiring type: Twelve-time Pro Bowl linebacker Junior Seau, who returned to the New England Patriots this season, said in remarks on Showtime's "Inside the NFL" that he has played his last game.

Seau first retired in August 2006 after 13 seasons with San Diego and three with Miami. But he signed with the Patriots four days later and played 27 games for them over two seasons. He retired again after the 2007 season, then came out of retirement for the final four games in 2008 before retiring after that season.

Seau played seven regular-season games this season, all as a backup, and made 15 tackles. In Sunday's 33-14 playoff loss to Baltimore, he had a season-high 5 tackles.

Crennel joins Chiefs: Romeo Crennel has agreed to become defensive coordinator for the Kansas City Chiefs.

Crennel's agent, Joe Linta, said that the former Cleveland Browns coach will start his new job in a "couple of weeks."
