They are not bigger- Michigan's average weight per their 2 deep of both lines is 306.5. Nebraska's is 306. Nebraska has a clear size advantage at the receiver and tight end position. We are not giving up size to Michigan.
Stronger?? No way to measure this objectively.
Michigan had serious depth issues coming into the season along the lines and brought in transfers to help fill the holes. Yes, their backups have more stars by their names but most are unproven.
The last time we played, both teams were completely different. Our last game against them was in week 3 of Scott's first year. Martinez was hurt but played about half the game. We had Bunch under center... this is the week after we lost to Troy. If you can go watch the Troy game and then any of our last three games and tell me we aren't a different team, you are crazy. Michigan was also a vastly different team. They won 10 games with their only conference loss to Ohio State.
Minnesota is a good football team. They might beat us again... but it isn't a guarantee and they definitely are not a superior team in measurables. They have played cleaner football and have better special teams. Those two areas will likely be the deciding factor in our matchup. If we play clean, frankly we are a better team and should win 8 out of 10 times.
It's almost as if you haven't seen Nebraska recently. We have big linemen, huge receivers, and have dramatically increased strength and conditioning. If our special teams was good this year, we would likely be a top 15 team sitting at 4-0.
