This is just my take, so take it FWIW...
Names the Michigan Rivals site is throwing out:
The usual suspects: Jim Harbaugh, Gary Patterson
The pipedreams: Sean Payton, David Shaw, Bob Stoops
The "Huh? Are we just listing every SEC coach?": Brett Bielema, Butch Jones, Marck Richt, Mark Stoops
The B1G scraps: Pat Fitzgerald, Jerry Kill
The realistic options: Steve Addazio, Jim McElwain
No mention of Dan Mullen or Les Miles, surprisingly. Named just about every other SEC coach. For what it's worth, the rumor is this is not as attractive of a job to those out there as it may be perceived by the Michigan fan base. It's obvious to me after that press conference that it is Jim Harbaugh or bust...but I just don't see him leaving the NFL for a college rebuilding project when he will have multiple offers from other NFL teams. Patterson would be a great hire but he has turned down overtures from other top programs before. Addazio is a guy who would be a great fit for their program, IMO. Florida might beat them to the punch for McElwain after getting the cold shoulder from Hugh Freeze (see what I did there?).
Other names I think they should have added to that list beyond Mullen and Miles: Teryl Austin, Pat Narduzzi, Chuck Martin
Props to Hackett for answering the Michigan Man question like this:
"First thing I'd like to do is get rid of that term, so maybe you can write about that today."
