Obvious question on Isiah Prince is whether he would even sign with Alabama, and the answer to that may very well be no.
For Alabama, though, the bigger issue is simply one of trust. UA extended a firm offer to him on the basis of him being a firm commit and cancelling all future visits. He accepts the offer and tells the UA staff that he is cancelling all other visits... and then he shows up in Columbus 48 hours later. For 'Bama, can the staff even keep a spot open for him, knowing that if he goes elsewhere it will cost someone else on the board?
It's possible Saban and company might do that -- OT is a need, of course -- but my gut instinct tells me that 'Bama probably just passes on this one now and considers the ship as having sailed. I would assume it's Richmond or bust at this point, with the odds being in favor of bust.
