Dominant bigs that the Warriors drafted... Green I guess, who they got in the 2nd round, and I'm guessing if he was a Sun and we were not winning a title with him BC would lament his lack of height.
Reaching for bigs is how crappy teams stay crappy. I don't think teams ever get burned more often than when they're drafting big for "need".
Anthony Davis is widely considered the league's best big man, he has never played a playoff game, he got paired with another dominant big in Cousins and the Pelicans only really hit their stride when Cousins went down with an injury.
Of the top 10 teams in the NBA there were a combined THREE All-Stars that play the PF or Center positions (Aldridge, Horford and Green), those same 10 elite teams featured TWELVE guards and wing players.
The top contenders have virtually all the best guards and wings, meanwhile having the best center doesn't even guarantee you a playoff birth.
I'm not saying I'd pass on Ayton, I think he is a stud, but it is a guard and wing dominated league.
