Ockham' razor would suggest it's more likely yes, but...
EK has said his injury has really only limited his lateral agility. His playmaking and hockey IQ, his speed have remained the same. So why does it look like those traits have been compromised?
Knowing his desire to win, his fondness for luxury commodities, you'd expect he'd be playing better to strengthen his stock for his upcoming contract.
Look at the skills competition, he should just literally walk away with it. His walking is most NHL'ers full sprint in terms of talent.
Something more is off to me.
