Lax, I'm not gonna go out on a limb and claim being smarter than you, as you generally have way too much info in any particular conversation, but......Frye is young, and while he played his ball at IU, he's from Elwood Indiana, which is east/northeast of Kokomo Indiana. South Bend is a stones throw from where he grew up, so conceivably he could of very well grew up an Irish fan.
You mentioned his stint @ BC......I believe in 4 of his 5 yrs there, his lines averaged over 200 yds on the ground. I'd have to go back and look up the stats again. His OL produced on the ground with lesser talent than what he'll have to work with at ND, you and I can both agree on that. I don't recall off the top of my head how they did pass blocking.
So.....he's 38, has done well in past jobs, from central Indiana......I'm not making a case for or against, just some of the things I've read about him. I'd be ok with him or a combo of Watts and HH as a hands on analyst if it came to that. HH has proven he knows what he's doing, and I do know he doesn't care to go out on the road pandering to 17-18 yr old kids. If that's the case, then bring in Watt to learn coaching techniques and nuances while doing the heavy load of recruiting on the road.
