3. Corey Kispert
It never hurts to add more three-point shooting in today's NBA, and Corey Kispert would be a guy to look for if Sean Marks wants a volume shooter off the bench.
As of this moment, Cam Thomas is the only volume shooter for the Nets, and Kispert is able to provide a similar game, but at 6'7" compared to Thomas' 6'4".
Kispert is currently shooting 39.4% from three on 5.2 attempts per game, after shooting 42.4% from three on the same number of attempts last season.
Kispert is in the third year of his four-year rookie deal, meaning he will have another year of control beyond this season. This makes it a similar situation as Caruso; however, Kispert's contract is cheaper since it's a rookie deal.
As long as Jordan Poole and Kyle Kuzma are leading the Washington Wizards, they are going nowhere. I don't know if they'll have the guts to trade Kispert as he's one of their more promising younger players, but he is absolutely a player Sean Marks should jump on if available.
