If playing with divisions and bye weeks, should be able to have the first round split by division with the top division winners getting the bye. This way rounds 1 & 2 you are playing for your division Title and then you Play the Other Division for the Overall Championship.
Don't just make the Division Winners Top seeded and then everyone else by record.
This will make more like NFL.

Customizable playoffs. I want a 5 team playoff to be an option for a 12 team league. I like the % of teams being 5 of 12 as opposed to 4 or 6. The way to do it is week 13 is a bye for 1st and 2nd seeds. Week 13 for seeds 3-5 would have a points matchup. Top 2 scorers advance. Week 14 resumes normal playoff format for matchups.
