I just had to add this one, and I can't imagine why I forgot it because I repeatedly comment on it during the game. One of the posters over at Dawgman added it to the list.
Garcia needs to make perfect snaps to Jake Locker.
This is probably the important thing you can improve on offense. Every time Jake has to reach for a snap, or go down and get a low one, it throws off the timing of the offense. If you can get this one thing down you are going to improve the efficiency of the offense by 20%.
Why that much you say? It is because the 1/4 second or more delay takes away a read from Jake Locker, maybe he can't make a great fake, or perhaps it makes him fumble the ball during a hand off.
It is all about discipline, and doing it right every time, that is what makes a football team win, and that type of precision takes coaching no matter what the talent level is.
