Celtics scored threes with incredible percentage in first half and played a great defense in last period. Even without Tatum they were very productive. Brogdon made an extra contribution. But they blew the lead in last 24 seconds. They had another chance to win the game but Williams shot 0/2 free throws and Cavs got a miraculous win in overtime. It's funny that these two teams' games went to overtime this season. Cavs won all three of them. It was like a preview of a possible Eastern semis. That would be a damn good series if happens.
