John Calipari credits a "tweak" to the Kentucky offense in early March for turning around their season.

Calipari blamed himself for not making the switch earlier in the season and he has been coy to reveal what has actually changed.

“When you figure out what it is, you’re going to say, ‘You should have done it earlier,’ ” Calipari said. “I’m here to tell you I should have.”

“I’m not supposed to talk about it,” forward Julius Randle said.

“Nope,” guard Dominique Hawkins said. “Can’t even talk about the tweak.”

College basketball analyst Tim Welsh says Kentucky has been playing less of the dribble-drive motion system and more designed offensive sets.

“It seems like John’s tightened up things,” Welsh said by telephone Sunday. “He’s been more controlling, calling plays. I think he’s taken a lot of the thinking out of the game.”

The result, Welsh said, has been “better spacing, better confidence.”
