1. Doug McDermott
Doug McDermott is by far the best three-point shooter on the Spurs. McBuckets can knock down the triple off a variety of looks, and he only needs an ounce of daylight to get his shots off cleanly against a perimeter defender. No one else can replicate his versatility and efficiency.
The veteran forward has come up in trade rumors numerous times over the last couple of years, but San Antonio doesn't seem interested in parting ways with him at the moment. McDermott is a virtual lock to shoot over 40% from deep, and he poured in 123 threes last season.
Everyone knows McDermott won't be a starter in San Antonio this season, but he can still be a crucial contributor off the bench with his three-point marksmanship. Doug can get hot in a hurry, which gives Gregg Popovich an ace up his sleeve when an opponent backs him into a corner.
