Wouldn't Lavin have to be fired or quit now to have any remote chance of getting a coach and a decent recruiting class for next year. I think most fans are tired of him but it goes back to is it better to keep him around for another year and hopefully build off a great year or buy time to find a new new coach.
No coach plus + no recruits = bad news
If he makes the tourney, he will go out "on top". Might even be able to get another coaching gig somewhere down the road.
If things go bad, he will create some kind of drama to make him look like some kind of champion of integrity and he will step down and find a TV job.
Sitting on the bench for next year's impending disater will only hurt his rep.
This is his last year. Book it!
