Why are the Dodgers such retards on the bases?

It's unfortunate these things don't get factored into players' statistics and made more known to fans than it currently is. You can blame the coaches for maybe telling them to take a step too much but in the end the blame should be placed solely on the player(s). I'm not a Dodgers fan so I have not been able to witness this first hand. It would be a shame if these types of mistakes take away from Kemp's All-Star performance thus far.
