things go poorly
Looks as though other schools including Texas, Oregon, and Georgia Tech (do they have the recruiting clout to do this?? edit: Talking about GT here) are instituting a similar policy on recruit visits.
Right from the old man's mouth:
"The thing that we will do is we have allowed the kids to commit and still look around the last couple of years -- we're not doing that anymore," Brown said last week on Signing Day. "If you are committed to us, be committed. If you're going to go look, we're going to go look."
