Better question:
Let's say you all get your wish and he's forced out. How long do you give the next coach to have us at the top of the conference, ranked for most of the year, regularly making the second weekend of the tournament, and sending multiple guys to the NBA?
My wish is for the program to return to national prominence instead of withering away into irrelevance. Whether KO is the guy to do that or not is irrelevant to what my wish is.
But to answer your question, if KO is canned, the next guy gets 3-4 years, as is standard. By next year KO will have had 3-4 years post-sanctions to put his stamp on this program.
In terms of the OP question, they're not going to get rid of him now, but there are major questions going into next year. Here's what I think for next year.
10-20, dumpster-fire type year: Fired after this year
Near .500, maybe NIT: Not fired, but clearly on the hot seat for 2019, with the expectation of being Top 25 or he's gone
Above .500, bubble team, new guys show promise: Off the hot seat, but would be right back on in 2019/2020 if that team doesn't get back to the Top 25
AAC contender and clearly in the NCAAT field: Great confidence in KO and he should easily achieve the Top 25 in 2019 goal
