and I think what you said is absolutely the right thing to say in the locker room and to the players. But from a strategist's perspective, when discussing building a successful program, I see nothing wrong with these comments if he thinks they are a missing ingredient.
In short, I don't think he should be worrying about hurting te players' feelings in this venue. I'm sure they're working like crazy to get bigger right now anyway.
Wise to be thinking from a players' perspective though...
