I went back and watched the condensed version of the game. Hornibrook was off, the receivers didn't help ton and eventually Michigan just wore UW down.
I looked at one inflection point where it got out of hand, a spot where a few mistakes cascaded, mainly on the drive that made it 21-7
-Defensive hold on a long third-down throw
-A Michigan fumble JUST slipping out of bounds
-Hitting the stupid snapper
-Getting hands on a maybe pick but not getting it
Then after the TD
-Taylor drops a first-down pass
-Davis doesn't run out a route as he looks for a holding call and can't convert a third down
That all comes in back-to-back drives of a tight game. If UW's defense is last year's unit, that can come out in the wash. Against a better team on the road when the tackling/discipline are hit and miss, it turns a maybe competitive game into a blowout.
Bonus play was Hornibrook putting a third down pass too far out in front of Davis on third down, then punting from the 43 down 14 with less than 18 minutes left. Didn't help that a second-team All-American lineman got walked into the QB's lap by a fifth-year reserve tackle.
(Also, the first UW pick looked like a play of aggression. Yes it was tipped, but the receiver just didn't look open enough, at least for a pass that took a minute to get to)
