I took heat last year for saying that we should get to living or get to dying (so to speak) at the OC position. I was all for Brian last year, untested and everything. If you listen to the players a big part of the run game improvement is that Brian has ALL the unit together in the meetings (IE Running backs, OL, etc.). I think he is basically a defacto Co offensive coordinator already. I also think part of the gig for Greg was to basically mentor Brian to get him ready for the OC spot.
Two reason I think/hope it will happen this offseason:
1) As I just mentioned above, that has been the plan all along for Brain to take over.
2) Why not hand the keys over to Brian when the offense will be fully functional and has the best chance to not only succeed, but flourish?
This year wasn't a success BECAUSE of Greg Davis, it was a success because of the players on the field. Greg is a good coach, and OC (Think Jake Rudock), but Brian in the future and is sitting on the bench and we aren't fully utilizing his talents right now (Think CJ Beathard).
