I know nothing of this player, nor of his situation with VT, so don't try to read anything into this.
But I do think this shows what many of us have long suspected -- that the further and further we move the committing time table up, the more and more you're going to see of people changing their minds. It just stands to reason that the more you ask less mature players to make decisions, the more often they will come to regret them -- and sometimes the program comes to regret it as well. Plus, there's just more time to think things over, more time to see how academic performance and playing performance records pile up, etc.
I certainly don't advocate for this but I have to say I am not at all surprised.
I remain OK with early commitments when everyone knows their minds, but I do think many players are jumping before they are really ready and that is not the right way to go about your business.
