Remember basketball is a mental game. The less distractions the better. That includes ignoring your #1 worst fans from the other team. The heckler just wants to get in your head, and make you lose your concentration on the game. Use their taunting as a reminder of how good it will feel after you win the game. Let it fuel you fire. I developed a habit of not even being able to hear what was being said in the stands. Focus on the game, your teammates, your opponents, what your next move is going to be and you may never even hear a specific fan, just the crowd as a whole. Good thing about summer basketball camps, there won't be any hecklers!
Definitely want to ignore this guy:
