I tend to put more weight on the "on court" vs off court... there are too many uncotrollable variables with "off court"... some teams simply have superior bench players.
When evaluating individual players I'll look at on court +/- and
efficiency ratings which includes more individual performance benchmarks (((Points + Rebounds + Assists + Steals + Blocks) - ((Field Goals Att. - Field Goals Made) + (Free Throws Att. - Free Throws Made) + Turnovers)).
At least with these stats you can get some defensive contributions.
I'm glad that we're finally becomming more intellegent fans... I hate when folks throw out scoring numbers as the major criteria.
