One of the reason Flowers has been such a great quarterback his whole life is because he believes in himself. When you play a position for a decade and have major success, why should you listen to someone tell you that you can't do it?
Texas wanted RGIII as a receiver and Johnny Football as a corner. Penn State wanted Jim Kelly as a linebacker. LSU wanted Teddy Bridgewater as a receiver. Southern Miss earmarked Brett Favre as a safety and let him play quarterback as a courtesy.
You could go on and on. The NFL (a.k.a. the guys who cut the checks) told Warren Moon he was a receiver and told Rich Gannon he was a safety. The only reason those guys were able to have so much success in their careers is because they didn't believe what they were being told.
Do I think quarterback is Winky's best long-term position? No. I see him as an NFL safety. But he's had enough success and has enough skills (including a rocket right arm) that he deserves a shot at quarterback. If he's not as good as Kaaya or Rosier/Eduoard, move him. If he's better than those guys, keep him there. Maybe Rosier should be a safety. He certainly looked good there in his highlights. Bring in the most talented, most productive football players and let them compete. Flowers is one of the best football players in Florida, and he should be here.
