I tend to think Fleck has gotten his program to the point where their valleys are going to be small. More like Wisconsin was for many years. Good teams lose good players -- and doesn't necessarily mean they'll be bad or even significantly worse.
He's already got his starting QB in place, as he started 5 games last season.
The Gophers are loaded at RB. Potts started several games two years ago when Ibharim was injured, and his numbers were great. Plus, they have a 4-star freshman RB.
The defensive backs were gone prior to the bowl game, so Fleck practiced with and started two freshman corners that apparently performed well according to Fleck (and that's the beauty of bowl games).
No doubt there's some holes to fill, but I doubt the Gophers are falling far. For a game one on the road, not easy. Fleck will have a system in place while we are still building. Purdue is much more in our situation.
To our advantage, however, Minnesota won't really know what to expect from Nebraska.
