Surprise pick for me but I'll go with it. We do need guards that are willing and able to play D. Don't know much else about him.
Stop me if you've heard this one already: the Kings played "historically bad" defense last year. And, IMO, the worst part of that defense was on the perimeter. Davion Mitchell isn't simply a great one-on-one defender. The WAY he plays defense, the PRIDE he takes in harassing people and being a difference-maker on that end promises to ripple throughout the team. (I'm loving the thought of DM and DW - and Davis, if back- paired up already.) Fox and Ty were already vowing to pick it up defensively. I don't think De'Aaron goes out there half-a$$ing it w/DM busting his tail every time down the floor.
We saw last year that the Kings *could* play strong defense. Mitchell makes it a lot more likely that team-wide defensive intensity will be the norm rather than the exception.
