Parker was pissed when George Hill was starting over him before, what makes anyone think he will be willing to come off the bench now?
Once Timmy and Manu officially say they are retiring the spurs need to figure out a way they can trade Parker and Diaw together. They can get something good out of that combo. Parker is not the future. Spurs need an elite point guard who can go up against GS, OK, Clippers, Blazers etc. They aren't going away and that is the strongest position in the NBA right now. Parker is just not going to cut it anymore.
