Supposedly ... pairings in February are based on highest NET rankings by teams in both leagues. Hopefully that is indeed the case, vs. trying to pair teams that haven't yet played each other.
Let's face it. For this to truly work and benefit teams for March, the February pairings, at the least, should be NET pairings. If that means some challenge games are with teams that have already played each other, so be it. The top 4-5 teams in each league may rotate position but overall haven't really changed that much.
If that means two straight road games vs. the same team, so be it. The object, in my opinion, is to pair teams with an eye toward March. Otherwise, what's the use.
