My first reaction to this is that Coach Mac, while we all love him dearly, is 70 years old and has been out of the game for 16 years (hard to believe, isn't it?) My next thought is that if this is true, DO IT RIGHT FREAKING NOW!!!! Don't wait. Make the move today. Honestly, if this is in the works, there's no reason to wait for this season to run it's course. Just do it. The assistants are all available. NFL teams don't start training camp for another 4 weeks. College camps don't start for another 6 weeks. If they are going to do it, now is the time.
