#2: Ausar Thompson
I'm sure I'll get some disagreement here, especially when it comes to fit, as Thompson is arguably the worst 3-point shooter in the NBA right now.
But Thompson is already a great defender on the verge of being elite and those aren't easy to come by in the NBA. Shooting is generally the skill that young players improve the most, so I do not doubt that Thompson can get closer to the league average as he gets more comfortable.
He's already a disruptive defender at four spots, and lately, we're seeing what type of weapon he can be on offense, as he has more space to get to the rim and has in recent games.
This is a league dominated by wings and skilled bigs, so the Pistons need to be hoarding as many of both as they can get their hands on.
Thompson takes the pressure off Cade Cunningham to defend the other team's best perimeter player and will fill the stat sheet without constantly needing the ball in his hands.
The Pistons are not a good team yet, but all good teams need a guy like Thompson. Just look at the impact OG Anunoby is having with the Knicks. Thompson is not near Anunoby as a shooter yet, but elite defenders make a difference and are harder to come by than shooters who do not defend.
