There were actually 2 in that game... might be because it's a weak punter in a league high enough to have players outrunning his punts... maybe as we see more speed and hang time kick in, we'll see them more? Before punters have been consistently outkicking the coverage, but now, my team can even keep up with some of my level 29 punter's kicks when hang time kicks in (I assume that's what the slowing down at the end is)
