I think they might know the college kids a bit better than our scouts and coaches. Johnson had the same edge, maybe, just maybe those two could get that same edge. I like Sumlin because anyone who could turn that UH team into something deserves a lot of credit. I watched most of their games and he did an excellent job working with the players strengths and weaknesses.
As for Shaw, I lived in Palo Alto when he was hired and watched/read everything about Stanford. He believes in the trenches and has a tough exterior. I mentioned him on here weeks ago way before that thread appeared.
Gruden - if Garrett is fired and Jerry wants a big name, he is the best of the bunch IMO. I especially do not want Lovie, so Gruden is my fall-back.
