In recent years, the quarterbacks that Norm Chow has coached include Philip Rivers, Carson Palmer, Matt Leinart and Vince Young.

There is increasing chatter around the league about what Chow could do for a team. The talk comes a week after Titans' quarterback Kerry Collins elevated his game during a high-scoring win over Houston, and at a time when Chow?s Titans are preparing to face Kiffin?s Raiders in one of the most intriguing matchups of the weekend.
