The Boston Celtics vs. Chicago Bulls series heated up over the weekend as the #1-seeded Cs went into Chicago and picked up two crucial wins to even things at 2-2. 

During Chicago's Game 4 loss, Jimmy Butler got into a brief spat with Marcus Smart which led to Butler questioning Smart's toughness after the game.

Simply put, Butler says Marcus Smart was only "acting tough" and he really "isn't about that life."

“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.”

“We’re not gonna sit here and get in each other’s faces,” Butler added. “Like I said, he’s not about that life. Calm it down.”

The pivotal Game 5 is scheduled for Wednesday night at the TD Garden in Boston.
