but seriously, Pot was an incredible grappler. If you consider the concept that a grappler is supposed to be great in there area (close range), and have a hard time getting in, then pot fits it then some. He not only destroyed at his optimum range (which was actually closer to mid range), but he had acutal ways in, and his ATG game was good, JD had obsurd priority. He also had scary anti air.
in comparison to tager, pot can actually get his best damage without having to rely on a random hail mary. there's probably more to say... but I don't really know the specifics.
