2012 rotation by the end:

Hill/Collison
George/Barbosa
Granger/Jones
West/Hansbrough
Hibbert/Amundson

2013 heading towards the playoffs:

Hill/Augustin
Stephenson/Johnson
George/Green/Young
West/Hansbrough
Hibbert/Mahinmi

Granger is obviously lost to knee injury, Augustin is worse than Collison, Jones was better than Green has been, IMO.

On the other hand, Mahinmi is better than Amundson, Paul George is MUCH better, West is better, and I think Roy is better.

I think Barbosa and Johnson are roughly a wash. I think Tyler's basically the same, sometimes he seems worse, other times he seems better.

I'd have to say that at first glance I think it's about a push, IMO. Better in some ways, worse in others.

Our defense is better, our offense is worse. But you might argue the improvement in D is more than the downgrade in O. Maybe.
