I'm involved in one of those 2 Zl1 team and I actually tend to agree.
I think a full season does need to be played to have promotion and relegation. As you say, pretty cruel for a team to get relegated when they have 6 points to play for. This is a personal opinion only though, my club may feel very differently.
That's right. I don't play for any of the teams in the relegation battle, but you look at all years gone by and there are upsets with teams fighting to stay up and it always goes down to the last day. No one has earned the right to go up or down until all games have been played.
It's football, not s***er!!
