I don't think our owners misjudged how the fans would take it. This plan put them in a bad position, the current status quo is to our benefit but if Super League got going we would have to be in it or we would become irrelevant.
Unlike Bayern or PSG they would have joined but would have been allowed at a later date, they can wait to see which way the wind blows and join 'reluctantly' later. As English teams were likely to be over represented we didnt have that luxury. Sign up now or forever outside.
If we sign up and it went ahead we were in. If it failed well everyone already hates us so we lose little. But the potential gains of failure should not be over estimated - removing a couple of senior UEFA executives who have previously tried to stop us, to cause PR problems at the established History clubs that the media love and who have actively tried to stop us (as part of the hateful 8 / 9), to reduce the ability of the big 2 spanish clubs to finance transfers. Our owners will have judged these things.
They didn't tell fans, or players, as it would have leaked. For all we know we phoned Cerafin to keep him informed, and to ensure that the snakes were removed - we dont know. By leaving first, with Chelsea (who I think are in a similar position to us with regards to this), we minimise our exposure as much as possible and allow UEFA to see us as the lesser of the evils.
Was this a good thing to do no, but it is totally understandable.
