I’ve no idea if he has or hasn’t EB, although I get where you’re coming from as it took me a good while to get over my second bout of Covid, but this is different and shows classic signs of aged related decline in sporting prowess/performance like I’ve mentioned above.
A big sign also last season for me was Kyle going up and down the flanks both defensively and offensively at lung bursting speed, sooo used to him having amazing/elite recuperative/recovery abilities no matter how many times he did it in quick succession, his level barely dropped, then, he did about 3 sprints (6 in total) in one game and he was done.
Have a read up on VO2max and how it affects endurance of athletes when they age EB if you get the time.
