GSW vs HOU series has made it very clear that ISO ball does not work. Their 1-3 are all great passers. Imagine Fox, Bogi/Buddy, and Luka on the floor once Fox develops his shot. Those 3 are fast/ create opportunities for themselves and others. 3 potential spots that can be surgical against any defense. Compared to Ayton, we've seen KAT and AD just get bounced out of the playoffs and they're top 5 big men in the league. Willie was good last year with Fox on P&R, so just imagine Fox and Luka feeding him! Capela is a player of circumstance and no reason Willie cant be as good as him.
If you watch Luka against OKC you can see that he's playing with urgency and an NBA type of a game. You can see his hustle and intensity on defense. Euro league games he looks for more opportunities on offense. This kid has the heart and he has all the time to develop his defensive skills, primarily because his offensive skills are so advanced for his age. Dirk, Porzingis, Markannen all were said to be too skinny, cant play defense, and they'll just get knocked around, but they're proven to be extremely productive players.
