It's a commitment to winning above all else.
I believe Tony Parker and I believe that he understands that while there are times that it will be crucial that he be aggressive and score -- early last night was one of those times, since nobody else could find the range and if Parker hadn't gotten those first 11 points, the Spurs might have been buried quickly -- and times when he needs to use his playmaking abilities to create opportunities for his teammates.
People can cast stones at TP all they want, but when it's mattered to the team, Tony has (in a variety of ways) acted in ways other than his own self-interest to be a good teammate. I've never understood the need to see Tony vs. some other Spur as an either/or proposition -- dating back to the Manu v. Tony days.
The Spurs are where they are because of Duncan AND Parker AND Ginobili AND Leonard AND others. Tony's statement is a testament to his understanding of that truth -- one that seems beyond the grasp of a lot of Spurs fans.
