No it won't. Probably a really good long term decision, considering money, schedule, recruiting, available coaches, and being fair to staff and players.
I believe beginning with the bowl game, we are going to see a return to a passing bias team, maybe 60/40. The reason being able to place more responsibility on receivers. He wanted to open it up, but couldn't with young receivers and inconsistent quarterbacking. Every time he tried he got burned, he will find a consistent qb from the 4 . Gunslinger attitude returns, nothing to lose, everything to gain now.
OC will help, loss of other coach won't hurt so much.
