Interesting. The description of the West play is just crazy. I always gathered there was a little leniency, but that's just silly. My understanding of an assist is that it has to lead directly to a basket. You can have a bunch of dribbles from a guy after he's caught the pass, so long as he's headed directly to the hoop (like on a fastbreak).
Another one I've always wondered about are the tipped rebounds. So often you see a guy end up with the on a rebound isn't the guy who really made the play. Posey and Big Baby seem to do a TON of this sort of thing - make a hustle play that keep the ball alive for a teammate, but not get the credit for the board.
