I am not going to make this a prolonged argument because I know no matter what I say, it isn't going to change your perspective on this matter.
But first of all, I said left them in limbo, as in, unprepared for the future, Kane is gone and now we have to try and salvage the season before it has even started because you know, losing a guaranteed 25+ goals from a team is a pretty big deal imo, especially two days before the first game of the season when he has been in the plans for every preseason game.
Also, I can't imagine the players were for sure ITK in regards to if Kane was going or not, he may have hinted he was considering it if the offer came in like he did with Ange but that's not exactly a sure fire guarantee is it?
Even Ange said "It looks for sure like it's happening now though" in his press conference and whilst he did say he thought Kane had pretty much made his mind up after their first conversation, his language above shows he still wasn't 100% sure before today.
