You can't just categorically disagree that it's part of a measure of a player's efficiency. I mean, they have the stat assist/TO ratio for a reason.

edit: And doesn't your argument also argue to simply have the league use 48 minute projections of every stat? The same way that Nash is penalized for getting so many touches, I think Jordan Farmar is penalized for not. It's part of the game, it's detrimental to winning, and it's correlated with touches. Not sure why this makes it a bad stat to include.
