Brick, good analysis on why blocks alone is a misleading stat. Besids the valid criticisim of uber-blockers being constantly out of position, the other simple truth is that a blck does NOT gaurentee a change in posession, frequently blocks go back to the offense who convert on the second chance. Steals on the other hand result in not only the loss of a chance to score by the oponent but a solid opertunity to score against a team who is not in it's defense. the down side of course is similer to your complaint about Cause being out of position, once a player goes for a steal and misses he is no longer in position to defend and has left his man open to cut, shoot or make an open look pass. Case in point would be young J Will who's entire defense seemed to center on going for the steal (and even when successfull often jacking up the stupid 3 instead of running the ball all the way down for the lay up).
So in short Steals per game is a bad single diminsion stat and so is blocked shots. I would love to see blocks per game expressed as a ration the same way that turn overs and assists are expressed. Ballanceing out steals is more difficult and would need to be divided into factors like oponents points scored or something equally essoteric.
