I think a lot of this whole discussion is based on how you remember it .
Do you remember Tmart as the blindingly fast, fearless playmaker pre injury? or 1/2 step slower guy who made bad decisions , commited turnovers , and took too many sacks ?
TA used as run first throw second limited decision role (Foster farm bowl game) was great . Or do you remember gimpy, post injury guy forced to throw constantly ? Yolo bombs and a maddening inability to hit a receiver 10 feet away ?
Gill was a great player in my youth, but I mostly remember he could never win the big one . To be fair though he didn’t have near the receivers we have had post Callahan . I think Westercamp, Swift , Morgan etc would have caught that 2 point conversion and changed history .
Memories of Crouch could be tainted by seeing him get rocked by Miami in 2002 (one of the best teams in college history ) or his not so good attempt in the NFL. I remember a dynamic playmaker with his arm and legs whose play won many games for us .
Berringer didn’t play enough for me to even remember his play but he was a great person gone too soon and I think that’s why people are ranking him so high .
Some of this is comparing apples to oranges too . Different offenses , different types of receivers and offensive lines etc all shaped how the qbs carreer went .
