Play Calling?

Does anyone have any info on the O.C. back ground? I don't get it. He had great play calls against La Tech, mixed it up very well. But then this weekend he did not open it up at all until the last part of the game. Four passes in the first quarter (3/4 completed) I was sitting with someone who played for Rice and he kept saying how glad he was we were not throwing it because there DB's would not be able to keep up. And we ran that draw up the middle all day and it never worked. Does Bennett not say something to him b/c he is a defensive coach at heart?
