The entire internet is checking out the article all at once, so I can’t actually open it at the moment (the Post’s servers must be taking a beating right now), but the basic idea is this:
Two more wild card teams in each league, for a total of seven playoff teams.
The team with the best record in the league gets a first round bye.
The team with the second best record gets to pick their choice of first round opponent of the three Wild Card teams with the worst record (the Wild Card team with the best record isn’t eligible to be picked).
