The nations far and away number 1 defense in Georgia is averaging 12 possessions per game on offense. BYU is averaging 10.3. How many more "opportunities to win" does the defense need to give them? Second half production as been abysmal from the offense. It has to change.
The defense needs more talent and Tuiaki is responsible for going out and making that happen. With what he has to work with though, he is doing a fine job. I think that guy has a lot of flaws, scheme and game planning is not one of them.
