Holtmann is pretty danged far from being in the hot seat. They finished 8th in KenPom this year, their best since 2013. He would have to have a disastrous season next year to be on the hot seat.
They should be pretty good next year. I also think they lose both Wessons. Unclear if they lose anyone else. They add Cal transfer Justice Sueing and Musa Jallow returns from his redshirt year. They should have a lot of guards and wings but not a lot of big men. Biggest question for me is development of Kyle Young and EJ Liddell. If they can add a solid three point shot OSU is a national title contender. If not not, may be hard get production offensively.
Like a regular NC contender? Or Big Ten contender?
Max is a lot more optimistic about 2020-2021 than I am, and I think that is the biggest (maybe only) difference of opinion here.
I think we all know that teams/programs have peaks and valleys. If Max is right and 2020-2021 will be as good or better than this year then Holtmann is fine and the program appears to be heading in a good direction.
I am not optimistic about 2020-2021. The Wesson brothers averaged a combined 60 minutes, 23.2 points, and 13.2 rebounds per game. I do not think that can be replaced with 60 more productive minutes.
Going into 2019-2020 I saw it as a "peak" year. If I am right then at this time next year Holtmann will have gone four years without a league title or appearance in the tournament's second weekend. His only team to have seriously contended for a league title was his first, with Matta's recruits.
As far as expectations:
I expect tOSU to be at or above their long-term historical average. That means roughly top three in the B1G. Right now, I do NOT think that this program is in the top third of the league. I think that MSU, UW, and UMD are all clearly ahead of the Buckeyes while IL, IA, M, PU, and IU are all about equal. That puts our program right around the middle.
