I think the Wizards and the Bucks show the athletic deficiencies of the Kings. When faced with those kind of teams it seems that the Kings are just overwhelmed by the length, quickness, speed and strength of their opponent. The Kings seem to have two very good athletes on their current team - Fox and WCS. They need more. It's something for Vlade to keep in mind as he makes future personnel decisions. It's ok now to currently have experienced but less athletic players to show the kids the ropes, but as the kids get more experienced I'd like to see experienced but slow and earthbound players be replaced by some very good athletic types. Kelly Oubre, for example.
Yep, they've accumulated a lot of skill players but not much athleticism. Vlade and Webber's Kings didn't have a whole lot of athleticism either but they had a ton of skills that compensated for that. What they gave up in athleticism on the defensive end, they made up on the offensive end with ball movement and pure scoring abilities. The current team doesn't have that. You're correct about WCS and Fox but Fox is so weak right now that he can't even use his athleticism half the time. Giles won't be as athletic as he could be after all the knee injuries but he should be in that group with WCS and Fox when he starts playing.
In the upcoming draft, Doncic is a lot of peoples favorite but he's the least athletic of the upper tier prospects. He's also arguably the most skilled. It's going to be interesting to see what happens.
