I really hope it's KO by mid-season. He was clearly making steps forward before his injury last year as a potent offensive weapon who could drill 3's at a high rate, take guys off the dribble, and has a vast array of moves to beat guys around the rim. He's a decent defender, and would pair perfectly with Horford, as I expect Brad to play him closer to the rim than he did last year.
Our defense is going to be very, very good regardless, and adding KO to the starting line up could make our offense a really potent threat, the kind it wasn't last year. There's questions about scoring from the 2nd unit, but I think Smart/Rozier/Brown is going to be better offensively than people would think. Plus, having JJ/Amir in the back-court provides spacing, defense and rebounding,
