Well, the problem is they are not good at defending the three.
The Pistons are the 12th worst team at defending the three. The three pointers allowed with no defender within 10 feet is like 10th worst, no defender within 6 feet is also about the same.
That is why the Knicks are a good matchup. The Knicks are the 12th best 3PT shooting team by FG%. But they never shoot it. They rank 28th in amount of 3PT shots.
The Bucks and Pacers aren't exactly huge threats either. They come in at 21st and 15th most shots.
