Any per minute statistic is only good for trend reporting. Conclusions based on per minute stats are irrelevant.
For example, based on this season's WS48, Jason Kidd and Jose Calderon are in the top 3 best Point Guards. Forgive me, but Rondo is clearly better.
I like total win shares as a statistical measurement, it makes KG the best player in the post-Jordan (Bulls) era.
yeah, i like win shares too, but as far as i understand it, it isn't fully fair because it gives the advantage to players who play lots of minutes, like john holingers per gives the advantage to those who take lots of shots.
actually, i totally think that if you were to look at rondo's position adjusted wins per 48 during last years playoffs he was actually pretty much the best player, with his paw48 being on par with lebrons. he was playing superstar level basketball.
i think during the regular season rondo has always backed off. every. single. year... and then in the playoffs he goes into overdrive. every. single. year. perhaps during the regular season kidd and calderon are playing better, but when it counts - rondo is actually as influential to a game as lebron.
and just by the by, i dont think it's a coincidence that new york start playing well the year they sign jason kidd.
