Thought this was interesting, he's telling his biggest recruits to keep quiet about their committment until signing day. In an age when coaches are rushing the process more and more, this seems to be a throwback. I think if coaches don't get their early signing period, this is the next best solution: simply keeping their commits secret until the very end.
The trend will likely spread to other big-time recruiting factories and I think it will have an interesting effect on schools like us. We could get wrapped up in continuing to heavily recruit kids who've already (secretly) committed and it will be more difficult to focus on kids who are still on the market. It could have a negative effect on our efforts, but it also could improve the recruiting process by not allowing rivals to (knowingly) poach each other's commits.
Imagine if PJ had kept quiet about his PSU commitment then Pitt couldn't focus on trashing just us in their recruitment of him -- for all they know he could be leaning toward WVU...
