Well, let's see:
Spurrier: Stuck his whole career behind a 49er great. Never given a chance.
Wuerffel: Drafted by a inept team and coached by a guy known for defense.
Best remembered play was of him looking through the ear hole of his helmet
"HEY, WHO TURNED OFF THE LIGHTS?"
Doug Johnson: Didn't even get drafted. Tied out as a free agent.
Tebow: One memorable season where he led his team to a playoff win.
Cut by a two-faced guy who wanted nothing to do with him.
Greatest college qb of all time but a flop in the NFL.
"TIM, THAT WAS GREAT! JUST HAVE YOUR LOCKER CLEANED OUT BY MIDNIGHT!"
Jeff "Ears" Driskel: Recruited by Charlie Weis, AKA "The Ice Chest Destroyer".
Blows Gainesville and finds a modicum of success
at some Louisiana school. Has bounced around the NFL for years.
Seems destined to always be a backup with little success whenever
he does sniff the field.
Trask: Time will tell. Has all the tools to be successful. In a position
to learn from the GOAT. In this post, Nova pointed out how that Spurrier, Wuerffel, Doug Johnson, Driskel, and Trask might have been great NFL QBs but he went on to explain why they weren't thereby helping make my point better than I did by actually siting the excuses/reasons why UF has no great NFL QBs.
