Copied from my post in Iowa recruiting thread (16 wins ties Woody).
KF is in a conundrum. He needs 17 more B1G wins to move into #2 in conference wins ahead of Woody Hayes. Assuming he gets 7 more this year that means he probably needs two more seasons minimum (I guess they could go 8-1 this year and 9-0 next). Ironically, that will probably cost him the 0.600 win percentage he needs for the college HOF. He can't get both unless he can go 8-4 or better the next two years when the schedule should get tougher. He will probably be at 0.5967 after this year.
If he stays through the 2025 season, he will need at least 224 wins to be 0.600. He is at 201, so the countdown is 23. Say he gets 7 this year, that leaves 16, thus the 8-4 or better required. If he leaves after next year, he needs 216 but he would have to go 8-1 this year and 9-0 next year to get the 17 B1G wins.
So, his options are:
#2 in B1G wins OR 0.600 win percentage which qualifies for the college HOF. Doesn't appear he can do both unless he can go 9-3 or so for next several seasons AFTER this current year.
