The 3P shot has it's place. Especially if it's used by players who can shoot from a distance. Trouble is, there are a lot of players these days taking 3P shots that can't shoot outside. And too often I see guys shooting a 3 with nobody near the basket, and without a single pass being thrown. That makes the game boring and inefficient.
Sharpshooters like Bird and Ainge used to take 3s all the time in the old days. But those teams still adhered to the old Celtics line of passing for the best shot. The line that has worked for Pop and other successful coaches. You hate to see coaches become overly dependent on the 3. It has it's place, but some players shouldn't be taking them.
