Indeed, Slaf has been playing very well, but his health is concerning, especially given that he seems to be dealing with the same type of injury that ended his season last year.
This is truly concerning because the injury seems recurrent. We know that Carey Price ended his career prematurely due to a knee injury, and Kirby Dach also missed the entire season for a knee injury.
Juraj, however, appears to be in great shape when he is on the ice, and it doesn't seem to be affecting him. Hopefully, it will continue this way!
