Synergy, Holy Grail of basketball information. To use it is to be addicted, to be addicted is to sometimes abuse it.
I’ve lately seen many a writer and reader cite Synergy’s individual defensive statistics as argument trump cards. Hey, this player has a stingy points per possession (PPP), contrary to your denigration of his defense. Hey, this player can’t be good at D with a total Synergy rating like that.

On Hang Up and Listen, Kevin Arnovitz cited how writers used Synergy to a good end. The Warriors trumpeted free agent acquisition Kwame Brown by referencing his “post defense” as an asset. Writers took to Synergy and checked Kwame’s data from those situations. Brown simply did not grade out as Kendrick Perkins of Charlotte, the numbers showed him to be below average at guarding the low block. This was a wise application.
