Another blown 14-point halftime lead. The five turnovers by Charlie Burgess.
"We had leads where we can dominate the second half in the last two games, and we didn't," Knight said.
The Red Raiders still won both games, at UTEP on Saturday night before their 70-60 victory at TCU on Wednesday night.
That got Knight within four victories of matching Dean Smith's NCAA Division I record. The next victory by the Red Raiders (6-2) will tie Knight for No. 2 on the career list with Adolph Rupp.
"If it hadn't been for people asking me, I honestly wouldn't know what it was," Knight said. "That doesn't affect me one way or the other. All that means is I've coached a long time and had a lot of good players."
Burgess made up for his turnovers with 20 points. That included six-of-seven 3-pointers, one of them starting the tiebreaking run midway through the second half that put Tech ahead to stay.
TCU used a 20-6 run and got even at 44-all with 10:40 left on a 3-pointer by Brent Hackett, who had started the second-half surge with another 3-pointer. But the Horned Frogs weren't able to go ahead.
Burgess then hit a 3-pointer and Martin Zeno scored the next five points to stretch Texas Tech's lead to 52-44. Zeno finished with 19 points and eight rebounds.
"Burgess was the dagger every time he stepped up," TCU coach Neil Dougherty said. "He really made big timely shots for them."
While the latest victory certainly doesn't rank as one of Knight's favorites, the coach actually found some good in what happened.
"Our main objective when we started this season was to be better than we were last year," Knight said. "I don't think last year's team could have hung on and won either of these games. ... We really had a tremendous bend in our play, but we didn't break. We came back and put the game in a position to win it."
The Red Raiders also found a way to win when leading scorer Jarrius Jackson struggled most of the night, playing on the same day that his grandfather died.
"He had a tough time. I'm sure that was on his mind," Knight said. "I think it's just a big thing that he was here to play."
Jackson finished 4-of-10 shooting for 16 points, 10 in the final 5½ minutes.
When the Frogs got within 60-56 with 2:15 left, Zeno penetrated before passing the ball out to Jackson for a 3-pointer. Jackson then scored again on Tech's next possession.
Jackson was only 1-of-5 shooting in the first half, making only a 3-pointer. He missed his only two free throws, after missing just three of his 46 attempts before that.
Despite Jackson's early struggles, the Red Raiders led 38-24 at the break.
Zeno and Burgess combined for 23 points on 9-of-11 shooting in the first half. Burgess made a short jumper about five minutes into the game that put the Red Raiders up 7-6, and they never trailed again.
