Don't get me wrong here, post players shouldn't be expected to handle the ball as well as their point guard can
. They should have the ability though to at least dribble effectively with both hands. If they can only dribble in one direction it's easy for the defense to catch on to this and completely shut them down by forcing them to their weak side. Post players that don't ever work on their dribbling skills are on borrowed time if they are still producing on offense.
