One huge issue is the speed of the D1 game. Practice is one thing ... and normally a lot slower than an actual game environment. Sure you can become effective IN DRILLS, but then, in a game, when you have to scan the field, evaluate the coverage, make decisions on what you're most likely going to do with the ball given coverage, then take the snap, manage the pocket, and THEN throw without thinking about footwork / mechanics etc. Like Spurrier said "only 25% of HIGHLY QUALIFIED HS QB's CAN MAKE THE ADJUSTMENT TO THE SPEED OF D1 BALL". It's a lot easier for an elite athlete to play TE than QB. We might be seeing that with Jacurri.
