Massey Composite seems to think there's a clustering developing that most(?) posters would deny (OSU/PSU/M as together followed by UW as separate). I'm just not sure. These next three weeks determine so much.

The computers don't distinguish Wimbush ND from Book ND, so I'm guessing they knock UM for that loss far less than posters do.

I mean, it's early, it doesn't really matter, but with Wimbush for another two games, Notre Dame beat Ball State by 8 and Vandy by 5 in a game they lose if the Vandy player makes a wide open catch.

In three games with book ND has three blowout wins, including a pair over ranked teams.

I'd argue it still doesn't really matter, that BYU is trash, but my guess, and I know it factored into my rankings until BYU fell apart, is that the Notre Dame we see now is not the Notre Dame we had Weeks 1-3.

Is Michigan knocked for playing Wimbush? I wasn't aware. Seems strange, though, given that - even if he sucked in all his other games - in that game his passes were atypically dead-on. Michigan didn't make or let him throw the best game of his life. Something else did. I'd argue it was dumb luck.
I'm sure Michigan would also love to face Book in a rematch now that they've shaken off the week 1 rust.

I don't know that I'm "knocking" Michigan for losing to Wimbush ND as opposed to Book.  I guess I would be if that was the difference between them and Wisconsin but it really isn't, ND either way appears to be far better than BYU.  
It is getting awfully subjective to say that an opposing QB just happened to have the game of his life against a team as opposed to saying that the opposing D just didn't play well.  I'm not saying you are wrong, just that if we start going down that road we end up in discussions of ridiculous minutiae that can never possibly be resolved.  
My thinking is that over the course of the whole season these sorts of things tend to balance out.  Maybe ND's QB had the game of his life against Michigan and maybe Nebraska (just in general) played terribly against Michigan.  Ok, if those things are true then Michigan looked worse than they are against ND and better than they are against Nebraska.  
If I rated Michigan based solely on their loss to (Wimbush) ND I'd have them #5.  If I rated Michigan based solely on their win over Nebraska I'd have them #1.  On average, #3.

I get that. But the reputation for Wimbush both before and after the Michigan game was that his arm is highly erratic, not accurate and that was consistent with his woeful comp%. Then he played arguably the best defensive backfield of his college career and consistently dropped balls into just the right place.
This is proof of nothing but is suggestive. I'm merely acknowledging that Occam would sooner say that he had a dumb luck day than claim that Michigan's defense is overrated. Especially since so many of Wimbush's - unusually spot on - passes were well defended that day.

My read of Michigan over Harbaugh's tenure is that the offense isn't very dynamic (though if they can get strong talent together everywhere they can be).  So against the better teams that are tougher to defend they struggle to win because they can't rely on the defense to grind it out.  They are certainly capable of running the table this year but need a lot to go right.
