Hence why it hinges on him.

As someone who has watched him all season he simply isn't playing at the level he was last year. Everything in him has diminished and it has come to the point where he is legitimately hurting the team every minute he is out there on the floor.

We'd be much better served with Farmar/Brown taking up all the minutes. The sad thing is Phil Jackson would rather lose than do that.
I noticed that he looks a step or two slower and has trouble keeping guys in front of him. That's what happens when players get older. Believe me, I know and have seen my share of them with the Spurs.

What's more curious to me is why PJ will not give more minutes to Farmer/Brown combo.
