It's the same in my league. We are 3 teams with 20-2 records in my coference, where the best team in the other conference is 17-5 - and is, probably, going to the finals.
If he gets promoted as a lucky loser, I think I'll stop playing this game. It is TOO random for me, I must say, where the better teams are.
Another problem is the on-going change of team owners. I just got a new opponent for my play-off game tomorrow. Some teams have changed owners 2 times this season!
I just don't get it .....
