Except basketball has never and will never work like that. You can't just add KG to the Mavs in '01 and expect the numbers to transfer across the boards. You add KG and the offense changes in such a way that Nash and Finley's numbers might go down because the flow of the offense would change based on KG's game. Dirk creates mismathces on the offensive side of the ball, opens up lanes and changes spacing in a way KG never could. I completely reject the idea that the difference on the offensive side between Dirk and KG is negligible, while the difference on the defensive side is a chasm. You can't judge offense by comparing 24 points to 21 and deciding that those 3 points don't matter much. KG is simply not even fukking close to dirk's level as a offensive genius.
Dirk flamed out once to an 8 seed, but just about every other playoff loss was to a very good team, even when the Mavs were seeded higher, in a tough Western conference where seeds 1-5 were all capable of making runs to the conference finals depending on who they matched up with in the playoffs. Dirk also - come rain or shine - made Dallas good for 50-60 wins
every year for a decade. In that sense, he was Tim Duncan lite. And KG doesn't have that to his credit. KG was done no favors by the Minny front office, but that still doesn't completely excuse all those years of not even making the playoffs.
Dirk won a championship against 3 future hall of famers including a guy who will be in the conversation for GOAT and another who will be in the conversation for top 5-7 shooting guards of all of all time, and he did it with old and spare parts. J. Kidd put up 8 & 8, shot 36%, and couldn't keep any guards in front of him on D. JJ Barea can barely contribute to the Wolves, and he was a significant part of that Mavs squad. Dirk's championship run was quite clearly and simply one of the most awesome runs a superstar has had.
I agree with @
Malta - you can easily build around Dirk. KG is the ultimate player to add to a team. Also, Dirk's skillset isn't one that falls off a cliff with age. While Struggle knees is shooting 35% and stinking it up in Brooklyn, Dirk is putting up 21 a game on 47% shooting, still. That's remarkable.
