Okay, listen close here...
Ainge could have his pinky finger amputated and it wouldn't make any difference in his ability to throw. It might affect his grip on the ball, but the pinky has NO effect on how far, how accurate, or how hard the ball can be thrown.
The reason there were no long passes is because the pass blocking was average at best. In the fourth quarter especially, Cal's defense was getting a lot of pressure up front and their DBs were sinking back into either a deep-3 or possibly a deep-4 to take away any possibility of long passing. Of course, it would make no difference because the LT wouldn't allow Ainge enough time to get a 7-step drop anyway.
Third, Lucas Taylor running an option from in close was a terrific call. The reason the play didn't work was because the DT (don't remember number) zipped between the backside guard and center; when #94 forced Taylor back inside, the DT (who should have been sealed off entirely) was there. It was poor execution up front that destroyed that play. Get the block, it's a touchdown. There's no excuse for a guard being unable to seal off a three-foot gap before a DT gets to the heel's depth. The center really should've just jabbed backside with his left hand as he advanced playside; it might have provided just enough of a delay to help the guard.
