Despite having a fantastic individual game on Sunday night, it's clear that Jimmy Butler has a problem.

Specifically, the Chicago Bulls star has a 6 foot 4, 220-pound problem.

Butler is being harassed by Marcus Smart of the Boston Celtics in their Eastern Conference playoff series, and it's working, as the team's will travel back to Boston with the series tied at two games apiece for Game 5 on Wednesday night.

Butler scored 33 points in 46 minutes during Sunday's 104-95 loss to Boston and took his share of abuse during the game, as he took 23 free throws, making 19.

The play that seemed to start everything was after a defensive rebound by Smart. Butler, who had missed the shot, was all over Smart as he tried to turn up court. Meanwhile, Isaiah Canaan snuck through and stole the ball for an easy layup.

Butler and Smart then had words and needed to be separated.

In the post game press conference, Butler was not shy about calling out the Boston agitator.

"He's a great actor, acting tough, that's what he does - but I don't think he's about that," Butler said. "And I'm the wrong guy to get in my face. So he needs to take it somewhere else because I'm not the one for that."

He was then asked if this was the first time Smart had messed with him this series.

"I think, yeah. That's the first time. Last time too. We're not going to sit here and get in each other's faces like that. Like I said, he's not about that life, so he needs to calm it down."

Butler has seen some things in his life, as he was basically homeless as a teenager in the Houston area. He then went to Tyler Junior College in Texas before ending up at Marquette. He's now an NBA All-Star, against all odds.

Smart went to Oklahoma State but is also from Texas. During his college days, he was famously suspended after shoving a fan in the closing seconds of a game against Texas Tech.

Smart had five points in 33 minutes but also added eight rebounds, six assists and five fouls.

But going forward, his most important contribution to the series is the space he is occupying in between Jimmy Butler's ears.

The smart money is on Boston going forward, unless something changes with Rajon Rondo's status. But Smart may not want to get Butler any more riled up, as that could get dangerous.
