When he doesn't get the block, he at least alters the shot (yes, there are times where they get the offensive rebound and put-back, but that isn't the norm). So, would you rather him give up an uncontested lay-up so that he can maintain position for the rebound? That makes plenty of sense. You say fewer block attempts=more rebounds for Jarvis. I say fewer block attempts=more points for the opposition.</p>
