Perhaps this is why there were so many "silent" commits early on, and why some people haven't commited yet. Jordan Diamond certainly wasn't ready to make that commitment. Neither were Darboh or Payton. But by them not commiting, and taking visits, no bridges have burned and they might still have spots in this class.
I wouldn't be surprised if others seeing this rule play out decide to take a little longer in the future to commit. But I like the precedent. Commitment has been getting to the point of being almost meaningless. By this reasoning, Hoke certainly doesn't consider Dunn to be committed to tsio.
