As Renard and others pointed out, we've played a ton of younger ones both this year and last. After the opener, there was actually a tweet about how many true freshman had already played. Last year there were new faces all over the place. And Franks and Trask are the same year, so it was never about true seniority. But yes, coaches whose job it is to win games will often gravitate to a player that has more experience, not to mention fits their mold better in terms of body type, much more so than a kid who hadn't started in a decade. If his hand was forced, like against Mizzou, so be it. But otherwise that's the route most coaches would take. Ironically, given the opponent this week, it wasn't until after Terry Dean threw his 20th interception against Auburn in '94 that known-moron Spurrier opted to play Wuerffel the rest of the year. And this was after the Uk win a year earlier where Wuerffel had bailed us out.
If the NFL draft were held tomorrow, Franks would be drafted ahead of Trask by a mile because every offensive minded coach would see the physical traits and drive and think they could be the one that get him over the hump. Unfortunately, he seemed to peak last year and never improved. But making it seem as if we went .500 because of him is wrong. At most, he was the difference(negatively) in one game, and had several others that his play contributed greatly to the victory. I agree that Trask makes us look better. But who knows what things look like behind practice doors. If the team truly felt that KT wasn't getting a fair shake, or that we were losing because of FF, there would've been chatter about it. Instead, even after miami, we got the exact opposite.
As for Pierce, I do tend to agree. I mentioned Saturday that I think the staff feels compelled to play him because he came back. Pierce, albeit usually against tired or backup defenders, has looked better.
I'll also add what ATX said. I could see Mullen just barking out names to someone who's frantically writing them down as he pees in a urinal. I don't read too much into it.
