Obviously, with three weeks to go in the season, the number of 5-4 teams that will be eligible for the playoffs is a complete unknown.
What is known are these two things:
1) Last year, 18 teams with 5-4 records did not make the field of 256.
2) Last year, 12 teams in the East Suburban Catholic Conference (5 total) and Chicago Catholic League (7 total) qualified for the playoffs.
3) Going into Week 6, with the new alignment for the Chicago Catholic League with zero automatic berths, 15 teams had records of 3-2, 4-1 or 5-0, which means a 2-2 finish in the final four weeks (Week 6 results not included at this point) would get more Chicago Catholic League teams into the playoffs than last season, and some of them are going to qualify with 5-4 records. And while it's possible that some of the current 3-win teams go bust in the final four weeks of play, it's also possible that some of the current 2-win teams take advantage of maybe the luck of the scheduling draw late and get to 5-4. The point is that the realignment has created scheduling situations so that MORE teams from the combined new league can qualify for the playoffs than did last season.
Basically, the view here is that the Chicago Catholic League will have more teams finish 5-4 or better this year than the CCL and ESCC had combined last year, so the view in early October is that several 5-4 teams around the state will again be left out of the playoffs and that the percentage chance of a 4-5 team getting a playoff spot as an at-large team have been zero in all seasons and that 2019 is going to be another year just like the 44 or so seasons before this one.
