I'll give the Knicks & Thibs credit
People say "Oh the Celtics just missed open shots in Game 1 and 2". It's not that simple. It's that the Knicks are baiting the Celtics to make 3 pointers. Sounds crazy to let the best 3 point shooting team to make 3 pointers. But what the Knicks did was bait the Celtics to take bad 3 point shots that was mainly ISO with no ball movement
They crowded the paint and ruined the classic Celtics ball movement, which is to drive and kick, made their offense funky. Pretty smart on Thibs end
