This is guy who was a top contender for gold medals for quite some time (and deservedly). He left the amateur sport (whatever that means) and after a stint as a 'pro' skater (whatever that means), he is returning to skate again (after 6 years) as an eligible. I believe all this is correct.
If he understands what he is doing and the Canadian Federation has no objection, then let it be!
How he will be judged in competition remains to be seen. I think the judges will be in for a difficult time if they hold him up. There are many talented young men who want the chance for a break through. I presume the judges at the Canadian Nats are all Canadians. Am I correct?
(As far as MK is concerned, she hasn't left yet, but that's another topic.)
