First, I also would like an expanded playoffs, but nobody could get together and make up their minds. There is nothing we can do about that.
Second, when it comes to talking about teams that may be better than they show out of the gate, I honestly don't feel bad for them. Every team has 60 games to play, they all know what they need to do. If they come out flat I'm not gonna be like "oh damn we need more playoffs for this team that blew off half the season to be able to get in"
Third, this may or may not be true. Bundesliga is managing this situation and they are still playing. The number might be substantial but it is not guaranteed like you think it is
