I don't think any player is a sure thing to stay at this point. I think Mason leaves, Maybe JD but that will the horrible with JD being a Cincy kid and loved playing for this school, MAW and Lahkin will go to a lower program if they leave so I don't see them leaving. I don't think DDJ will transfer again, not to mention he speaks very highly of JB.
I think Banks will get a scholarship, I do not think Vogt will be back, (god I hope I am right on that)
As for the AD making a statement, it takes time to get all the facts, He has to talk to John and the players to get all the info he can before coming out with a statement to save face. If he comes out and supports John and there were things going on behind the scenes he didn't know about then his job would then be up in the air to. I agree something needs to be said but I also agree you only get one shot at making this statement so I am sure he is working to get all the facts from both sides
