I've said this before, but I think Jareds familiarity with the system and his experience with is from HS will be a big help to him and will be a big factor in his development and eventually help him out a lot as a starter.
Mizzou benefited in the same way with Chase Daniel. I'm pretty sure he played in almost the exact same offense from his freshman year in HS through college.
It will be a good battle next year between Barnett and Tiller. Tiller might get the nod based on game experience and athleticism, but I think it will be tight.
I am so pumped for football!
