especially consideting he had no Spring, no Summer, very limited Fall reps. He was thrown into a system mid-1st-game of the year, a system he knew nothing about, didn't have the skill set, and was ablebto put up points and move the ball.
Then, Anae ( I think he did a great job doing this) had to scrap EVERYTHING they had been doing all Spring, Summer, and Fall and implement a new system on the fly, which b oth Anae and Tanner excelled at.
Now we have some reports now that Tanner is struggling with the offense, an offense that is designed for the type of qb with Tanner's skill set, and after he has had all Spring, Summer, and Fall to learn it.
