If the best team gets a bye, then there are 5 teams left. Using your example, the playoffs would have 6 teams, playing 3 games between them. Which leaves 3 teams for the next round. Are you suggesting that the second round would give a bye to the best team?
I'm thinking that you really either need to take 4 or 8 to the playoffs to make it easy, or you take 7 (Top 2 plus best other) and then you can give a bye to the best team in the league for the first round.
