At this point drawing a line in the sand if where the season ends in my mind is just kind of ridiculous.
If you want all matches played, if there are more postponements, teams have to play mid-week plus the weekend. Not fun, but sadly necessary.
If not, then shift to win % like last season. Right now NEC is down 4 matches. Considering they would be fighting for a Final 3 berth, I would prefer that all of their matches are played. All teams minus JT and Hitachi have 19 matches left to play.
NEC has a two match advantage right now, but by not playing those 4 matches, 2 of which are against the team immediately behind them in the standings is just wrong. Two wins by Hisamitsu would essentially put them at a tie, minus the two matches against Ageo. Let alone if Denso also tied NEC with two wins. If the gap was bigger like JT to Toray right now, then I would have no problem saying win %.
