Kelly I'll give you. Outside of his 2 years on the offense at Oregon
I can't really find a "great coach" that he would have learned from though.
When did he coach with Osborne? You mean the fact that he was a QB under Osborne? Some guy name Tommie Frazier played for NU once upon a time as well, under that same old stiff - and why don't you ask Doane how great of a coach he is? Epic disaster.
Are you talking about Bill Walsh or am I missing another Walsh - can't find one that he coached w/? He was at Stanford as an 18/19 year old when Walsh was there...but I certainly doubt that qualifies him as an OC. Did you follow the Walsh coaching tree about 18 branches to make a connection? Or was this another one where Frost played for a coach who happened to get his pool cleaned by the same guy that clean's Walsh's daughters fish tank? Regardless, I'd rather he had no connection to Walsh and his west coast offense, we've had enough of that crap here.
Might as well throw Parcels in there as well since he played special teams on a a Parcels coached team. I bet he sucked up 99% of Billy's genius during that time.
Or how about Callahan? Bill Walsh tutored Paul Hacket, who discovered Jon Gruden, who ultimately trained ol' Callahan. I mean Frost is definately qualified to be an OC now.
