I say you're all a bit off. It's all about Boris' best friend, Tony Parker. This is what really needs to be looked at.
Parker signed his extension with the Spurs, November 2004 at the age of 22. The previous season (his 3rd) Parker averaged 14.7 ppg (44.7% shooting), 5.5 assists (2.4 tos), 3.2 rbs, .8 stls, .1 blks and 34.4 minutes per game. Before the Spurs signed his extension, they were trying to trade him so that they could sign Jason Kidd because they felt Parker was too "Inconsistent." However, when the Kidd signing fell apart they came back and gave Parker $66m over 6 years.
So now we have Parker's best friend and French national teamate (who was just named the captain over Parker) at age 24 who just came off his 3rd season where he averaged 13.3 ppg (52.6% shooting), 6.2 assists (2.3 tos), 6.9 rbs, 1.1 blks, .7 stls and 35.5 minutes per game.
Well, I don't know about you, but if you had to choose between these 2 players at this same point in time, who would you pay more money too? Parker got $10m a year from a Spurs team that refuses to pay more for players than other teams. I'd think that based on this, Diaw will get around $11m a year - except here's the real kicker. If Diaw believes in himself he'll pull a Wade and LB and sign a contract with an opt-out after 3 years so that he can also re-sign for a much higher amount after the next bargaining agreement. So they may have to give him a Nene type contract to get him signed long term.
So that's my theory - It's all about Tony Parker. This is what we should be looking at because this is who he is talking too for guidance.
