In Friday's Bulls victory, Jimmy Butler missed 11 of his first 15 shots and then buried a tying 3-pointer with 48.2 seconds left in regulation, a go-ahead jumper with 9.1 seconds left in regulation and scored seven of his 22 points in overtime.
In Saturday's victory, Butler missed his first five shots, had three points at halftime and finished with a triple-double of 18 points, 10 rebounds and 10 assists.
"That's an elite player," Dwyane Wade said. "It's not going to be a perfect game all the time. You have to know how to be great, to make a difference. I saw it earlier in the season where he had some of those bad games and in the fourth quarter, he still made big shots. A lot of guys don't have the mental toughness to do that."
Butler has been a big part of the better ball movement that has defined recent victories. The Bulls tied their season high with 34 assists against the Cavaliers, their second straight game over 30.
"He just made winning plays, the right play. And that's what it's about," Bulls coach Fred Hoiberg said. "We talk about moving the basketball and trusting your teammate. And Jimmy's obviously a huge part of that."
