with this logic, then you could make a case that T-Mac > Duncan, because he never had the kind of talent surrounding him that Duncan had, but was a significantly more gifted and talented basketball player. but we all know what a dumbass argument that would actually be, because facts are facts.
yes, various situations do come into play to an extent, but lets not forget the fact that these are all professional basketball players. if you have a team that wins 55+ games, that team generally is capable of winning a championship. if it wins 60+, it should be among the favorites to win a championship.
Robinson had plenty of chances, and didn't even get to a ing Finals.
Dirk had chances, got to the Finals twice, and won once.
The compe ion point is crap, because both had to go through tough compe ion. The Mavs had a damn tough road to the Finals, beating teams that used several styles of play (Portland tries to win with physical play, Lakers try to win with their well-rounded play with a dominant player both in the post and the perimeter, OKC was athletic and fast-paced, and Miami would attempt to overwhelm you mentally with super-talented, seemingly unstoppable players).
Dirk took everything that was thrown at him, face- ed it, and did his very best to help his team win, whether they needed him to score inside, score outside, draw offensive attention to help teammates, or increase the intensity on defense and rebounding. And its not like its the first time Dirk has been doing this. He's been doing this stuff for years, especially ever since the GS series. The Mavs may have flamed out for those few years since, prior to this year, but in each and every series, even in loss, Dirk played his ass off and did everything he could do to win. This year, that at ude of his finally paid off, as it seemed to rub off on his teammates, and they all really stepped their game up as well.
