"(I laughed it off) a little bit,” Williams said to reporters after. "I joke around because where I grew up is different. So I was like, ‘Let me relax and go on and keep playing, just what my team needs.' "
The No. 22 overall pick added he respects Allen as a competitor.
"He’s a competitor," he said. “Don’t take anything personally. I’ve always thought of it as you wind up in the game, things like that happen. So you respect him, he’s a talented player. He’s a guy who did really great things at Duke, he’s good friends with a couple of my friends, so I didn’t take it personally. It was just a matter of competing on the court."
The Celtics will face Allen and Memphis again on Saturday in the quarterfinals.
