I think I agree with Wijg at this point, just rip the band-aid off, fire him after the tournament is over and let us fans know he isn't coming back next year.
What's the difference? We can lose just as ugly with one of the assistant coaches in charge as we can with Hewitt.
Better yet, they should just clean house and let Lamar and John Vaughan coach the team for the rest of the season. At least those guys should remember what it's like to be well-coached.
