My tiers would look a little different, at least for 2021.
1- MU/Covington - these 2 should go in with expectations of making the playoffs. I think the winner of this game is league champ this year.
2- Riverside/Miami East - these 2 should be hopeful for a strong year and a playoff spot.
Did East have a one-year blip?
Can Riverside duplicate their success against bigger (better?) competition? (last 2 seasons, 16 of 20 games were against d7 schools. They will have more games this year in league against bigger schools (5) than they had in the last 2 years combined (4). MU and 'Ridge are d4, Bethel is 5, Cov and ME are 6.
The difference between "hopeful" and "expectant" might be small, and I wouldn't be entirely shocked if one of these schools won the league.
3- Lehman/TC/Bethel/Northridge - Need things to fall right to make the playoffs.
TC beat Northridge last year 21-14, I'm not putting them a tier above yet. I love their coaching though, so maybe they can do it. The Miami East and Riverside games will be huge for them.
I hate Bethel's OOC schedule, so I don't think they have put themselves in a good spot for the playoffs. If they win those though, they jump to the front of the line.
Northridge has a scheduling problem too, I missed it before but in years when they can beat Oakwood and Carlisle, the rest of the SWBL is going to beat up on those schools and they'll be worth very little. Maybe Dixie can get them points in the WOAC?
Lehman hasn't shown much recently, but 2 of their wins last year were over Ridgemont and Ridgedale...so Northridge should be worried
