I look at his free throws as the main indicator. Manu doesn't have to be in his prime to hit them yet his percentage is declining. To me that indicates that his heart is drifting away from the game with other outside priorities taking his interest. There is nothing wrong with that. That's just the way it is and the Spurs are bringing in new blood in hopes of compensating as much as possible. Someone besides Parker will need to add to the assists off the bench on a consistent basis. Who will it be?
