Jae Crowder was not having the best of nights on Tuesday. He was missing shots he normally makes. There were some decent plays made defensively, but the game-altering, momentum-shifting hustle plays that he pulls off weren’t happening, either. Yet when the game was on the line and the Celtics needed one basket to win, they turned to Crowder. And the 6-foot-6 Crowder came up big for the Celtics as he drained a game-winning jumper from 20-feet out to lift Boston to a 95-93 win. After the game, Crowder explained what happened on his game-winning shot with 0.8 seconds to play. “IT (Isaiah Thomas) curled off me,” said Crowder who had nine points. “Right when he curled off TZ (Tyler Zeller) sets the back screen on my man. We knew they were going to get the switch but not quick enough. They were playing with two bigs at the time. So I got the corner shot.” The play called at that time had multiple options.
