Nobody's saying that his decommitment is a good thing, or a positive sign, or anything like that. Obviously he's exploring his options (quite possibly with his h.s. coach in his ear due to Borges getting canned). Michigan's situation is precarious, to say the least. We all get that.
But it's quite a leap to go from that to declare "I don't think he's that interested in Michigan". A Bob Beamon type leap.
