Bobby Knight, colorful and controversial basketball coach, abruptly resigned as head of the Texas Tech team in mid-season. He claims he just got tired and it was time to go. Some fans have speculated that maybe there was another incident that was being covered up, but we'll take him at his word.

LUBBOCK, Texas — Bob Knight took another swipe at the referees after resigning as Texas Tech's basketball coach in the middle of the season.

"Well, I won't have to see any more bad calls, that'll be one thing," he said Tuesday on Minneapolis radio station WCCO-AM.

The winningest coach in Division I men's college basketball quit Monday, turning over the team to son and designated successor Pat Knight to finish the season. Texas Tech next plays Wednesday night at Baylor.

"It really wasn't a very tough one," Bob Knight said. "And so with that in mind, I just thought it was time for me to step down here and let him take over this coaching job here."

The 67-year-old Knight, whose Hall of Fame career is highlighted by three national championships and countless on-court outbursts, said he's ready to quit battling the refs.

"I mean, we had some horrendous officiating in games this year," Knight told Minneapolis Star Tribune sports columnist Sid Hartman on the radio show. "And I think that really, to me, has never been a part of the game, but this year it just seemed to bother me more than at any other time."

Knight had promised that when he finally decided to call it quits at Texas Tech it would be hard to find him. He was true to his word Monday.
