You do realize we have two players averaging 20+ and one that just averaged 30? Not to mention, a more versatile guard in Brogdon already making a similar salary? Yes, shooting is always nice to have more of, but Simons doesn't do anything else well and there are only so many shots to go around.
It would be nice to have another guard on the roster since Pritchard might be unplayable in certain playoff matchups and Brogdon's health is always a question, but preferably it's not a one-dimensional scorer. Preferably they get someone with more of the other skills like playmaking, ballhandling, and defense.
