I'm trying to figure out how 235 career regular season NBA minutes has somehow become "three years later"?
I dunno what folks expect sometimes. He's a #16 draft pick. His rookie year production was fairly nominal for a #16 draft pick. The last 9 #16 draft picks produced an average of 0.49 Win Shares. Yabusele produced 0.60. The last 9 #16 draft picks averaged a little over 300 minutes. Yabusele played 235 (plus another 48 in the playoffs). Four of those guys played more. Four of those guys played less.
One (Royce White) of those 9 guys was clearly not made for the NBA long term but most are at least rotation-quality: Nikola Vucevic, James Johnson, Just Nurkic, Luke Babbitt, Terry Rozier, Lucas Nogueira.
I'm not saying Yabusele will turn out to be as good as Nurkic of Vucevic or that he won't be out of the league in a few years like White. But it's almost certainly way too early to be certain of either outcome.
