I don't have a problem with it because I understand the way recruits think...
Fans think recruits are supposed to be excited about sitting on the bench for 3 years, but that's not how it works. When you're a premier player & you have dozens of schools vying for your commitment it makes no sense to go somewhere you won't play vs somewhere you're guaranteed to play.
It has nothing to do with being scared of competition, it's about looking at the depth chart practically & making the best decision for yourself that will get you on the field the fastest & to the league the quickest.
We really don't have much to worry about in this scenario because Cam definitely isn't coming back after this season & maybe Amari doesn't commit to Miami, but even if he does, all Coach Hickson has to explain is that Thad will still definitely be able to play early.
It simply comes down to the staff not being dumb & doing what's necessary to sign the best RB in the state, just reassure the kid that he's gonna play & he'll stick, if not you'll hand him over to your in-state rivals.
This is recruiting, fans have to stop thinking the kids are fans like them to, they're independent contractors & it's their job to find the best place for them, the staff has make sure they do their job & convince them Miami is the best option.
