For anybody who was wondering at the time about any reasons for Warriner leaving, he seemed to confirm the reasons by a recent quote. Seems like those thinking he wanted the opportunity for advancement and play calling duties were right. Found this on a press release for his job at OSU, which includes run game coordinator/ co-offensive coordinator duties.

“I’ve always strived to coach in positions where I have a lot of responsibility,” Warinner said in a statement. “Serving as a coordinator goes beyond just coaching what my guys are doing. It is a thought process of attacking and moving the ball, and strategies and reading plays. There is a big picture as a coordinator that I am into and really enjoy, and it’s a position from where I think I can make a significant contribution to the success of a team.”
