While transition offense isn't the Knicks' game and they like to play at a slower pace, they would be smart to take transition opportunities when they present themselves. According to Synergy, the Celtics were the 2nd-worst transition defense this year in terms of points per possession allowed.
Opponents shot 43.8% on transition threes against Boston. The Knicks ranked as the 8th best transition offense in PPP and shot 41.8% on transition threes, though the pace they play at is generally very slow. I'd be surprised if the Knicks came out running and gunning but they'd be smart to run a little bit if they have the chance to rebound long misses and push the ball.
