I agree with what ManuTim said in regards to Dirk's POV
The thing is, Duncan has missed several clutch shots over his career (end of game 5 against detroit in 2005, end of game 7 against dallas, even if people do want to say he was fouled but whatever its the end of a game 7)
I even remember during games 3-6 of the 2005 finals people were saying duncan's stature in history would be diminished if he didn't show up in the finals with a complete disregard to what he did for the team in 1999 and 2005 (though admittedly I was amongst the doubters)
So my point is, I think when Dirk does miss clutch shots now and again it's amazing how harsh people are to jump on him. It's almost a shame that people will arguably think of the last year's finals and probably the phoenix game as oppose to what he did against san antonio in round 2 last year, or the many many occasions he's gotten his team a basket in clutch situations. I may not be a fan of Cuban, Stackhouse, or Terry but when it comes to Dirk I really admire his will to win.
And that's really all you can ask out of a player, is to show some heart.
So while I might cringe seeing Cuban's smug face hoisting the Larry O'brien trophy I will sure as know that Dirk earned it when it comes to his ring.
