Let's be 100% truthful here. Keller isn't leaving after this season unless he is hired away. The school is not going to cut ties after this season. His seat may be warm to start next season, but he is getting another year IMO.
As for his performance, I'm still at a cross roads. It is well documented that he has eight scholarship players available, and he only plays seven of them (Sorry Gru). That thin of a lineup isn't going to blow out a lot of teams, but should win some low scoring, slower paced, grind-it-out type games. More specifically, it is Danny-ball that will win games for this team this year. For the most part, I think that is what we have seen, without the same level of discipline that Kaspar demanded of his players.
I'm all for giving another year. Get another set of recruits in to help build some depth and right the ship. Hopefully TJ comes back, and we pair him with Kevon, Mitch, John, Nathan, Oddyst (His game is really growing on me. Plays just like Aaron, but much more aggressive offensively), and a healthy/more prepared Jock. Then you add the incoming freshmen in Hart and Pope and talent will not be an issue. We all agree he needs to add another PG to the class. If he can't win with that, then he isn't the man to help continue building this program.
As bad as this year is and as infuriating as it has been, next year will be the real litmus test on if Keller is the man going forward. Three years in and we still see a mixed bag. That has to get straightened out one way or another...
