I thought this was rather amusing. I think we all hope he proves doubters wrong and absolutely lights it up this year. That was the first I had heard of Kovalev's wrist injury, so that could be a rather good reason why he seemingly refused to shoot last year. If he's fully healthy and has something to prove it could bode well for us.
I've always been fine with players playing as long as they can in sports. If they can hack it at the top level, keep doing it until you can't. Just don't put everyone through retirement drama like Bret Favre every off-season.
Reading that article I couldn't help but think I wish it was Alfie saying he wanted to play until he's 50.
