Borges said this at a presser this week:
The approach hasn’t changed in 27 years. I script less plays than I used to. I script about 25. Now I script about 17 or so.
M ran 9 plays on offense in the first quarter, and then 10 more on the remainder of the possession to begin the 2nd. Give or take a few plays thrown in situationally during that time, Michigan's ability to move the ball ended when the script did. The obvious exception to this were two identical fullhouse Denard sweeps leading to a TD to end the first half; whether those plays represented a desire to go into the half down 14-17 that was thwarted by Denard's awesomeness is perhaps up for debate.
It seems that Borges takes great care in drawing up plays in preparation for the game, but then is extremely limited when it comes to adjusting on the fly, or seemingly even in remembering the basic gameplan. I was very impressed that Borges showed a willingness to not even test the middle of OSU's defense in the first half. It was exciting that he seemed to understand that M's interior OL was severely overmatched as he attacked the edges and stretched the D vertically. Needless to say, it was disappointing when he threw all this out in the second half.
It may be that OSU's D adjusted, leaving the middle looking so soft that Borges couldn't help himself. I don't think that's the case, but it sure didn't work either way.
