I never want to be a Hevesy apologist, but here's my theory:
This may be too simple, but if our staff had to choose between a 3* OL recruit with a great work ethic and desire, or a 4* premadonna who has all the talent in the world but needs to be coddled during recruiting, you know which one they are choosing. I'm not saying it always comes down to that clear of a choice, but I do think Hevesy (and Mullen) take the hard worker/underdog guy all day every day, and that they can develop that guy into a solid lineman.
I'm not saying they're always right, but I don't think they give 2 ***** if they recruit high profile guys or not, as long as they get the ones they like. In fact, I think if you asked Hevesy, he would say he's an ******* up front so he runs the guys off that can't hack it early, then he can then focus on the other ones. So, the "Hevesy can't recruit" thing just seems like a lazy way to complain about missing on a kid. It's just way oversimplifying it.
Teams miss on guys all the time. I like 5* recruits too, but we can't all be Bama.
