I like Simone, but Sexton is our hardest playing player.Simone is a two way wing (rare commodity) and is better than Grimes IMHO. He is an upgrade and Thibs will love him - he's our hardest playing player. JC is secondary ball handler and can adapt. JC + Simone together is a huge boost to NYK bench.
You do this and you trade KO to the Sixers for a million 2nds. Maybe you get in on the ATL action, maybe you do LAL. Lots of choices.
