Huh?
Quick Comparison:
Seasons: Mason - 10 years, Fleck 9 years (with one year being a Covid season)
Record: Mason 64-57, Fleck 66-44
Big Ten Record: Mason 32-48, Fleck 39-40
Record vs. top 25: Mason 8-32, Fleck 12-21
Record vs. Iowa/Wisconsin: Mason 3-17, Fleck 6-12
Mason took over a rougher program but it wasn't like Fleck walked into a great situation.
The way Mason ran the program has no effect on Kill and/or Fleck's successes.
I like Mason, but PJ is better in pretty much every category, except Mason had one more win vs. Iowa.
