That's a good start. Do what Nebraska and Northwestern did this year, improve by a handful of games. Other teams are going to change drastically. We don't know for better or worse at this point. If we don't make the jump, Johnson is likely out.
Well, assuming we win at Nebraska then we would be 3-17 in Conference.
3-17 is dead last (14th) place in the conference.
Looking at this year's standings:
It would take 2 to 3 more wins to reach 13th place.
It would take 6 more wins to reach 12th place. (9-12)
It would take 7 more wins to reach 11th place. (10-12)
Your argument doesn't move us more than two places from the cratered bottom of the conference. That is not good enough, period. Time is of the essence because this is about the program's recent track record, not one coach's record. Ben is living in a hole that was started by previous coaches. He is not filling it in. He is digging deeper.
We can't rely on other programs to get worse, even if you do the the upside to any change is +2 places in Conference. That doesn't get us out of the bottom half of the conference.
So, your plan doesn't improve the optics of Gophers MBB in the eyes of recruits. It also guarantees a worse 4th year as the program doesn't appear to break out of the basement. This makes it even harder to recruit from HS or the TP.
All signs point to either firing Ben now or becoming a nationwide laughingstock for another decade.
