I think Regan should go. I don't really believe I've heard a whole lot good about him and have heard his personality isn't the greatest. Maybe that's wrong, I don't know him personally, but that's just what I've heard. I know he recruits locally to the degree his position allows him to do so, and his brother is now a Judge but it's probably time to move on. I think he wanted bumped up when Smoke was hired, he even told a couple people he would be. It's pretty telling that he wasnt, IMO. As Matt said a few weeks ago, that position is usually used as a stepping stone for guys like Richards, but Regan has been there for awhile and has blocked anyone else from getting the position.
I think Barton is going to move on. He's been rumored to be doing so for the last two years. I would guess he might be ready to move on himself. He has done a decent job the last few years recruiting juco and 5th year guys but the ceiling should be higher than that. I think he should be replaced, at least his position is a recruiting one even if he isn't technically the top assistant. Replacing Regan does nothing to help recruiting bc he cant really recruit off campus.
