Yet, even as he has secured his first starting job since high school, Cassel can't escape other quarterbacks' shadows. When he was introduced Friday, the first name mentioned wasn't his but Jay Cutler's.
"It's weird," Cassel said, "because I didn't have anything to do with it. I was just a name in the mix, I guess. ... Unfortunately, that's how the NFL works sometimes.
"Jay now is on a different team. (Kyle) Orton's on a different team. Everything works out in weird ways in the NFL."
No weirder than Cassel rocketing from a guy who didn't start a game in college to a hot commodity in the pros. A backup for four seasons at USC and another three in New England, Cassel was thrust into the limelight when Patriots starting quarterback Tom Brady went down with a season-ending knee injury in the 2008 opener.

And every time the saga was mentioned, so was Cassel's name.
"I still don't know how it all went down," he said, "but that's football for you."
Last year, Cassel was little more than a trivia question: Who is Brady's backup? Now he's going into a season as the projected starter in Kansas City.
"My preparation doesn't change from being a backup to a starter," Cassel said. "I've always pushed myself and taken great pride in what I do. From that standpoint, it's no different than any other offseason. But there definitely is a feeling of urgency that you want to get out there and start on the right note and get some wins under your belt."
