Basically, promoters thought that an authentic and relevant league, that had some resonance, and ran during the warmer months, would negatively impact their unauthentic, and largely irrelevant league, with minimal, if any, resonance, (that they would still run), using the colder months too?...
In summary...
"This product would deliver what many fans want, and would engage them to attend, but then they wouldn't turn up to watch the usual contrived stuff we cobble together each season"..
They probably wouldn't be wrong would they?
