Have you ever been watching your favorite NBA team, and when a player on the opposing team is getting ready to shoot a jumper, you've already accepted the shot is going in?
Chances are, that player can be classified as a sharpshooter. These are guys who, when given any sort of open space, can knock down shots from anywhere inside 30 feet. They may not be the best at creating their own shots, but they can definitely get them off.
Sharpshooters don't even have to be starters, typically every team has a guy on their bench who is a long range specialist.
This free agent crop has their fair share of sharpshooters. For purposes of whittling down the candidates, this list includes only unrestricted free agents and are filled with guys who play a pretty decent amount, though most don't start.
