I think a healthy Taysom can do things with his legs that Tanner will never be able to do. He is in another league as a runner. And as good as Tanner's arm is, he is not in another league as a passer (yet). Of course, Tanner has progressed faster than Taysom did, and his decision making has been better than younger Taysom. However, I think senior Taysom is light years ahead of younger Taysom. There is something about a senior quarterback that finally has the feel for his offense. BYU hasn't had someone as athletic in that position since Steve Young. I don't want to miss it...
