A big running game in a SP offense doesn't mean we'll run the ball 50/50. It means that he'll be more privy to run the ball 3 or 4 times a game where he would typically pass it because he has confidence in the run game. SP has also talked about efficiency when running the ball.
If he feels the running game can get him 4-5 ypc when he needs it he'll be more privy to run it. However in our down years we've average significantly less and thus his thought process is simple...why hand the ball off for 3ypcs when i can just put in Drew hands in those moments and pretty much get an easy 4-5 yd completion.
Thus you get 3 or 4 more passes a game where we could have run it but there was no confidence in the run game.
We'll still be a pass 1st team as we've always been, just hopefully you can slash into those extra passes with some runs because you are confident you'll get consistent yards.
