Player of the game: The Celtics had Jimmy Butler under control – until they very much didn’t

There's a common saying around TD Garden - don't poke the bear. It usually applies to hockey, but the Celtics, and particularly Grant Williams, would have been wise to remember it on Friday night. Through the first 42 minutes of the game, the Celtics managed to keep the Jimmy Butler - who was the main reason the Heat won Game 1 and has been on a tear this playoffs - relatively in check. To that point, Butler had 15 points on 7-of-17 shooting, and was a minus-2 for the game. At that point, the Celtics led 96-87. That's when the Celtics poked the bear that is 'Playoff Jimmy.'
