On offense, Patterson and McCaffery won that game for Michigan last year, with their feet, in my opinion. They had 160 yards rushing and scored 2 TD's between them. That's huge.
The running games were essentially equal, outside of that. The receiving yards in that game were a wash. Only UW (!) scored a receiving TD.
M's defense scored 1 TD on a return from a terrible AH interception.
I think this game will look different because:
UW will have a DL play with full depth (minus 2 starters last year, and subs were young - one was an OL playing DE) and experience.
UW now has experience in the secondary - very young last year, and they got a lot of experience.
UW QB play will be better. AH was terrible all season.
UW WR play will be better. Losing Cephus was bigger than anyone thought.
UW is much deeper than last season.
None of this means that UW will win. They just won't lose 38-13.
