I agree we shouldn't bash Durant, its the NBA's fault super teams even happen in the first place.
Having said that, there is something to be said for the idea that just pursuing championships regardless of how you get them isn't commendable. Achievements aren't measured in a vaccum, their worth is determined by what you put into them and how hard it was to get there. Joining a 73 win team and winning a championship is not that laudable of an achievement not only for KD but for the other Warrior stars. And please lets not compare them to the Heat big 3 or the Celtics Big 3. Its not a fair comparison at all, Lebron joined Wade on teh tail end of his career and that Heat team didn't have anywhere near the depth of GS, same thing with the Celtics
