If you had coaches that were incompetent and actively hurting your chances at making it to the League, would you encourage HS kids to come join you and be subjected to the same thing?
I certainly wouldn’t.
Now, if this mystery WR is telling kids to go to another specific school + bashing Miami as a whole, that’s definitely a bridge too far and I won’t defend it.
But if he’s simply saying “Hey man, things are a mess here with the coaches. Not sure you really want to be a part of this. They probably won’t use you properly”, then I don’t think it’s the end of the word.
