IMO the game ball goes to the D line.
I know you've got gardner playing his heart out with a hurt leg, and putting together a drive for the go ahead points to boot, but there is no way UM even stays in that game without the D line pressure on CH all day. I think I counted 7 sacks. too lazy to check the box score.
I'd also give a close second place vote to the O line. Yes you read that right. I thought our O line played extremely well (relatively of course).
