Before we get into round 4, a determination needs to be made on which 24 teams advance. Exactly 6 teams from each half of each league will advance to round 4 (the four playoff teams and the teams with the next two best records). Also, per rules, no person can have more than 2 teams advance.
If anybody has more than 2 teams that are *qualified* to advance, the lowest ranking team(s) are dropped and the half-league (the dropped teams are from) will get a the team with the next best record to advance. In no instance will a half-league get more than 6 teams to advance to round 4.
The 24 teams will be ranked by (1) W-L record over 162 games (2) Expected Winning% (3) Home field win%. Any teams that get "moved up" from non-qualifying to qualifying status due to somebody having to drop teams, those teams will rank behind the qualifying teams, regardless of their W-L record.
