I’m sure he will play regardless of his underlying conditions, having everyone self isolate for 2 weeks to start training camp and then keep everyone being in the same hotel & arena is not rocket science; I think there is minimal risk. The risk for Kakko is also low regardless of those conditions given his age and health, among people 25 & under the death rate of the flu is 7 times higher than covid-19. He’s much more likely to die in a car crash on his way to the arena than of covid-19. IIRC Kakko has also said that he was surprised when diagnosed with diabetes & celiac as it wasn’t until a few years ago and he also said he never experiences any symptoms nor does it interfere with his life. So perhaps there are milder forms of these diseases. Type 1 is nothing like 2, and celiac has nothing to do with covid
Anyway, if he’s been seriously training during this time (pretty sure he has according to what we’ve seen social media & the fact the lockdowns were less strict there) I think he’ll look more like WC Kakko than NHL Kakko. He went the distance winning gold in every tournament and played a ridiculous amount of games, most of which were against men. He was dominant in the WC against NHL players, skating circles around Ryan Suter making him look silly I don’t think he just regressed.
