I think Masai has done a fantastic job with what he has been given and the reality that is operating a small-market team in the NBA. I hope he isn't shown the door. Now with that said, they should be looking high and low for a replacement for Karl. I don't want to throw him out if there is no talent but he has proven time and again that his players succeed despite him when the playoffs start.
And for the love of God, please find an actual two way center or power-forward.
