When I was coaching, I would offer (both positive and negative) opinions of various programs that recruits were talking to. I'd never just bash one with out saying something positive.
Such as, X University has struggled to field full teams in the past, but academically they are very strong and I know the athletes really like it there. Or, they are really good team, but aren't ranked very highly academically, or they don't have the facilities that we have.
I'd do this as a way to give the recruit questions to ask other programs, while presenting how my program is different and better for them. This way the recruit knows or can find out about each situation and can better find the right fit for them.
