Harden was on the team for a few of those years.

Harden was a rookie averaging 9 ppg in 2010 and 12 ppg on 2011. The team got better on offense in 2013 after Harden left the team and had their best offense in 2016

Ibaka was an All-NBA defender.

And that's relative to the teams offense how?

And they had a bench.

As does every other team in the NBA. BTW, outside of Harden who left in 2012, who was on that bench? 21 year old Reggie Jackson? 39 year old Derek Fisher? 36 year old Caron Butler? Enes Kanter who was traded for scraps? Dion Waiters who's playing his way out of the league? Cam Payne who literally played his way out of the league?
