I'm glad to see that we're talking conference wins. There's not a lot of Coaches given the opportunity to go from 4 wins to 2 to 9. Any Coach? or Coaches that are on their 1st head coaching job? Coaches let go because of "infractions" are not being considered. Any other "goalposts"?
Ernie Kent (Oregon 1997-2010) comes close. Fired after going 2-16 to 7-11(+5). He led Oregon to it's 1st conference title in 63 years. 2 Elite 8s. 5 NCAA's, 2 NITs, at the time of his firing all-time leader in wins at Oregon. But at the end, +5< +7.

I haven't spent a lot of time on this topic (post-season tourneys, high school post-season, transfer portal, etc..... are a lot more interesting), but it seems like most (not all) of the People that have low win totals on their resumes eventually get fired.
