I don't disagree with you - it's completely sketch and my opinion is what has happened hasn't followed the letter of the law. The problem is you aren't going to prove it. Neither girl is going to say what really happened and I'm sure the people he sent as his messenger/negotiator aren't going to rat him out either. To be fair - it's not just him that operate this way and like I said before: coaches talk and you don't want to be that guy, especially when one day you're going to need a favor for a meet entry, etc. You aren't going to get it if you're the one who's poaching athletes.
To be honest it's incredibly stupid to do it with Barnett because you've now messed with Vin. People have lots of opinions on Vin, but he's still Vin and he carries a lot of weight/power. He isn't someone whose bad side you'd want to be on.
I suspect Brosnan is figuring out that the hardest part of college coaching IS the recruiting side so he's using what he knows/has at his disposal vs going into the grind.
