Mavericks head coach Rick Carlisle has taken the blame for Thursday night's fourth quarter collapse against the Celtics, which resulted in a home loss.

"When you sit in this chair," Carlisle said, "there are times you have to be man enough and you've got to be honest enough to say that you blew it. ... This one's on me."

Carlisle admitted that Dallas should have placed more pressure on Paul Pierce, who scored 18 of his 31 points in the final quarter.
