Supposedly Matt Wyatt confirmed that Mullen called the plays in the 2nd half against UAB.
When Russell throws the ball, it actually spirals and doesn't take forever to get to the intended receiver only to be three feet too high on arrival causing the receiver to leap and get annihilated on the way back down. Also, Russell is smarter than Relf. He just is. There aint no two ways about it. I would love to see Dan take over offensive play calling. That is, after all, kinda what he is good at.
