If he wants to consistently go 7-5 or 6-6 then go to ND, but if he wants to compete for a B1G championship year in and year out then you come to Nebraska. B1G schedule>Notre Dame schedule
ND is not, seemingly, going anywhere... but they have a new coach and a new hope.
NU... just when do you envision that NU is going to compete for a B1G championship? Certainly, this year we did not --- we finished behind Michigan State and Michigan --- in our own division --- and behind Wisconsin and Penn State in the other. NU was 6th in conference... or, at best, 5th (depending upon how you count it). That is certainly not competing for the B1G championship.
Next year? Michigan is on a huge, observable upswing ... getting better and much better... quickly. Ohio State has the most talent in the league, by a good margin... and now has the coaching too. Watch out. Wisconsin and Michigan State may drop some. The best, the absolute best one could envision for NU (a team that has not shown any improvement over the last two years at all) is that they might match with Wisconsin or Michigan State next year and have a "battle" for and compete, potentially, for #3 or #4 in the conference. There is absolutely no reason to envision NU competing for a B1G title in the foreseeable future.
The point is, neither ND or NU are competitive or relevant on the national scene. Both are historic programs with a glorious past. Both have big fan bases. But neither is currently a force on the national scene or in any way threatening to win anything overly meaningful.
