On offense, Minnesota's o-line is large and powerful.
On defense, Nebraska (according to the article) is quick, agile, fast and unpredictable.
If you are Minnesota's offensive play-caller, do you opt to have your bigger, stronger offensive linemen...
A) Backpedaling in pass protection, trying to locate and engage with quick, aggressive defenders who are coming from unpredictable angles
....or....
B) Charging/surging forward, relentlessly, in front of our quick, agile running backs?

The best answer seems almost too obvious. The problem, of course, is that if it's obvious to us, then it's obvious to Nebraska as well.
On the other hand, does the Nebraska defense have the personnel to stop a powerful run-first attack even if they know in advance that it's coming?
