7feet 240lb guys who don't put up big offensive numbers -
Andrew Bogut
Timofy Mozgov
oh hey weird those are the two starting centers in the NBA finals. Bogut is certainly ABLE to put up numbers, but his role doesn't call for it on GSW.
More guys:
DeAndre Jordan
Tyson Chandler
Rudy Gobert - Jazz improved a lot when they traded your boy Kanter and started Gobert.
Actually, I think that's a fairly valid way to look at this Kanter as Kaminsky, Gobert as Stein. Utah played much better once Kanter left. OKC missed the playoffs with Kanter putting up the best numbers of his career.
Offense at the center position is not a requirement for a winning in the NBA. Defense often is.
