I doubt AA is going anywhere. Regardless of where he is projected.
I want him to stay, but it has nothing to do with him "being a legend", he's consider one of the best backs NU has had in history even if he doesn't take another snap. He has back to back 1000 seasons and one is our first 1500 rusher RB since, what Green maybe? He has been a consistent threat for defenses for two seasons. He has nothing to prove, in the means of being considered a legend.
I want him to stay to enhance the team next year, not because he's is the only option, we will have multiple weapons and if he's to go, I have no doubt Newby/Taylor/or even Cross/Frazier will step their games up. That is the nature of the backs at NU and what Coach Brown births through his teaching.
Again, I'm not too worried about AA leaving as I have a strong belief, we will see him working out in Lincoln during Spring camp and ready to lead NU in the fall.
