After being fired by Indiana, he became the basketball coach at Texas Tech six months later in 2001.
He led the team to five 20-win seasons in six full years.
That record made him the winningest Division I mens basketball coach at the time; he now ranks sixth.

He was 102-50 at Army.
Knight was inducted into the Basketball Hall of Fame in 1991.
Indiana officials tried to mend fences with Knight but were refused by the coach.
