"The rankings do not take historical achievements into account, purely a team’s performance from last season. The general result of this is teams that do well, will achieve higher ranking than their overall position in the pyramid, whilst teams that do badly will see their ranking suffer as a result.
It’s not intended to be a serious, definitive list – it’s just a bit of fun that provides a topic of conversation during the close season"
You see, just a bit of fun, supposedly.
