I understand your points and agree to an extent.
Obviously you've taken the time to try to make sense of this mess. Fair play.
The rules regarding self isolation have changed somewhat now and I do suspect they will be loosened further in tbe coming weeks - once the numbers start to come down (my guess - and it is purely a guess - is that this will be in mid/late February), so whether we'll really get a repeat of 2021 is anyones guess.
Its certainly worth understanding why the likes of Cas appear to have been in the position they have been, and to get them to change their 'standards' and 'behaviours'. What I don't want to see is players put under pressure to play when they either have covid, are in the recovery phase or are self isolating in line with government guidelines (player welfare etc). We already have too many players playing through the pain barrier for the sake of the team. (The number of end of season operations is quite frightening).
I know you're not suggesting that.
It may come to the stage where we all have to 'live with it' - but I could imagine some further restrictions put in place. (Not lockdown as such though).
Anyway let's see. I think there will be a few more twists and turns before the season starts.
Not aware of figures for the players not vaccinated.
In soccer it's about 25% from what I last heard a few weeks ago.
I did hear rumours of players not being allowed to play unless vaccinated because of the nature of contact sport. Interesting times.
