Quinn struggled to get past Derek Anderson to become the starter in Cleveland, but once he did, he showed signs of brilliance. Quinn threw for 304 yards and four touchdowns in a game against Detroit, for example, but had his 2009 season cut short by a foot injury.
It'd be nearly three years before he started again.
He was traded to the Denver Broncos for Peyton Hillis, now his teammate on the Chiefs, and a couple of draft picks. He lost out on the starting job there to Kyle Orton, and Tim Tebow claimed the backup job last season, leaving Quinn searching for a place to play in 2012.
He wound up reuniting with Crennel and offensive coordinator Brian Daboll, who had just been hired by the Chiefs and who worked with Quinn during his final season in Cleveland.
Now, it appears he'll be pressed into duty against the Buccaneers.
"This league, if there's one thing I've learned, you have to take things one game at a time," Quinn said after practice Wednesday, "and that's how I've continued to prepare myself."
Crennel hasn't officially ruled out Cassel for Sunday's game, but it's a long shot at best that he'll play. Crennel said he only spent a short time at the practice facility Wednesday.
Cassel had been struggling mightily this season, completing just over 58 percent of his passes for 173.6 yards per game. He's also thrown nine interceptions against five touchdowns, and has been credited with five fumbles, giving him 14 turnovers overall.
Only the Philadelphia Eagles have as many turnovers as a team.
So it's possible that Quinn would have gotten a chance at quarterback even if Cassel had not been hurt. Now, the decision appears to have been taken out of Crennel's hands.
"Quinn has to get ready to play. He's going to take reps today. (Ricky) Stanzi is getting ready to play," Crennel said. "We'll go from there at the quarterback position."
