Against a Bucks defense designed to take away everything in the paint, the Celtics managed almost no production there. They actually shot better from behind the arc (18 for 50) than inside it (10 for 34). “ You gotta be smarter,” said Jaylen Brown. “You gotta be the smarter team. (In Game 1), we weren’t. So we look at it, we learn from it and we come back better for the next game. … We shot a lot of 3s tonight. A lot of them were great looks, but we understand that’s what they want us to do. So we’re gonna figure it out.”
