The reason to have a regular season is to seed the teams. The number one team will face the #6 team, #2 vs #5, #3 vs #4. It gives the best teams the easier match-ups. Having only 4 teams in the playoffs is lame in a 6 team league lmao. There shouldn't be any bye weeks either.
It also gives the teams that performed poorly one last chance, even thought it'd be a long shot to beat the best teams in the league.
