The Facts: In his first stint with the Titans, McCareins learned the NFL ropes with help from some of the team's veterans. After agreeing to terms on a one-year deal with the Titans on Wednesday, he envisioned himself in a different role this time around thanks to his familiarity with offensive coordinator Mike Heimerdinger. "I think I could be a help to a bunch of the receivers who haven't had a chance to play with him," McCareins said.

Diehards Line:The Titans drafted McCareins in the fourth round in 2001 and in 2004 traded him to the Jets for a second-round pick. McCareins had his best seasons with the Titans under Heimerdinger, who was also offensive coordinator from 2000-04. It remains to be seen what kind of role McCareins will have on the field this time around, but he'll have an opportunity to contribute on a playmaker-starved offense.
