1. Derrick White
He had a rough shooting start in the preseason, but Derrick White usually takes a while to warm up when beginning anew anyway. When he gets his feet under him and doesn't have to worry about staying healthy, a confident Derrick White is a dangerous one.
White's career 3-point percentage of 35.7% is respectable but should probably be a little bit higher. He's had several nights where he hits five or six threes with ease, even pulling out some stepbacks back in the NBA Disney bubble. He's also probably the most complete 3-point shooter on the team when it comes to being able to shoot spot-up and off his own dribble.
Derrick is also highly effective in the mid-range when he goes to that shot -- knocking down 45.2% of his shots from between the 16-foot mark and the 3-point line. That number has him above every Spur besides Bryn Forbes in that regard (Keldon Johnson also has a higher mark but his attempts were extremely limited in year one).
Mix in Derrick's ability to get to the rim and create shot opportunities for himself or others, and there's no reason he shouldn't lead the team in shot attempts this season. He has the most complete package offensively on the team, and he needs to prove that by seeking his shot as often as he can.
