Pretty good answer by the head coach.

When you are game planning or putting your together misdirection is something you are always looking for, striving for. I remember sitting in a room in Dallas and game planning and misdirection runs and how our fullback takes us to the run all the time. Having to sit there and think we really need to do 'this', we need to run the split belly, we need to get away from the fullback and we need to do some of 'these things.' I think the Wildcat it takes you away from some of those things and gives you the misdirection. In other words you are not going to follow the fullback in the Wildcat and get the answer. Sometimes he isn't even out there. Those kind of things, the kind of misdirection and the use of it, strong side run, weak side run, downhill run. I think that is what makes it most effective. I could care less what other people think of it, but that is the answer to your question."
