I don't think Devo was runoff by Boeheim, but by the SU administration. Harris was an odd duck and I think JAB told him he was going to lose his minutes to Wes and that if he wanted to stay he could, but he would be coming off the bench for limited run.
I find article odd in that Kaleb's former coach is saying that JAB is running him off to free up a scholarship, but as far as the public scuttlebutt goes, SU isn't even looking at another G for 2016. There's an open scholarship for a big, which SU is looking for, but I haven't seen any rumors for a guard. So if JAB has already targeted a guard to replace Kaleb in 2016, it's being kept far beneath the radar.
