This is CJ's team. Jake is gone. Not even working out with the team. Who are they going to yank him for? Also, we know that KF does not replace QB's easily. Once you're named the starter, you are it until injury or it's the last thing he can do before shutting down the entire program.
I think CJ will open up the offense more, assuming he doesn't have to run the freaking OPTION 40x a game. We have some game breakers in Smith and Duzey...outside of that, we don't really know.
It might not even matter if CJ can't stay upright. Breaking in brand new tackles is going to be the key to the season for this team. That, and on defense can we find anyone that can tackle or defend the edge?
We won't learn anything in the spring game. GD will talk about throwing down field more, using the TE's....and maybe that will come true with having a QB who isn't afraid.
