I would expect any recruit with multiple offers to at least want to see who the next coach is before definitely following through on a commitment. Same thing happens everywhere. Georgia has a couple of super high ranked prospects (main one is Eason, a QB), and they are doing the wait and see thing too. The recruits should still love the school they attend overall, but the coaching staff is still going to be part of it.
I don't get wrapped up in recruiting news but it sounds like Hayes is a player I hope we keep in the fold.
