Good question...
A) I think it is too early to prioritize recruits other than by those that have offers and those that do not. And even those that do not should not be considered "Plan B".
B) I don't think it is fair to use "Plan A" and "Plan B". A kid without an offer who comes to camp and puts on a show and earns an offer is not a "Plan B" player. Or a kid who puts together a spectacular senior season and earns himself an offer is not a "Plan B" player. Guys like Major and Beachum could fit into that category. Some guys just take longer to develop or to show their talents to the staff and thus take longer to earn offers.
C) Despite JT's three-tiered recruiting approach, LB recruiting in particular is interesting beacuse you have to take into account what position they project at. Hale looks like a MIKE to me, whereas Sweat looks like a SAM. I suspect there may be a few other LB offers that go out at some point if in fact guys like Hines and Moeller end up at safety, as has been speculated. The staff may project Beachum as a WILL but want to see him in person before deciding if he is the WILL they will offer.
