The counter-argument is that because points are assigned by ranking the categories, teams that are not making roster moves affect the rest of the league as well.
Dat's true. Well, if you can find out for sure if they're definitely not playing, then maybe you should step in. Maybe give them another week to respond, and if they don't, delete their team and make their players free agents? (or just make the team ineligible for scoring)
