I'm not completely disagreeing with your take on if a recruit is capable of keeping a silent commitment or not, as some have shown they are. My only point was, a lot can't or won't.
Not sure KU has the luxury to slow play many of these guys right now. Maybe with a few.
Beaty would not have to do a silent offer and silent verbal for recruits that OU would find on their own. He would just do it for HS OL and HS DL recruits that are under the radar where he wants to try and keep them under the radar. These would be players in states that OU does not recruit as heavily where they are less likely to notice them.
As far as slowing down the rate of offers for HS OL and HS DL what I mean is that Beaty could wait a little longer to offer players that he wants to keep under the radar. That would make it easier for the recruits to keep their word on a silent verbal because it would be closer to signing day when they actually give Beaty the silent verbal. The less time they have to keep the secret before signing day then the more likely they are to keep the verbal a secret.
