When z and d are healthy they are most certainly elite. But you can't say the top 2-3 players in the league are elite only. Z and d are no longer top 2-3. You have stamkos Crosby Malkin Tavares toews who are all in their prime.
I was trying to be sarcastic, but yes I agree. I think Degrass backed himself into a corner by claiming that only 2-3 players are elite at their position. Heck I think there's at least 5 "elite"goalies in this league. And since there's 30 starting goalies in this league that means that theirs 60 top pairing D-men, and I believe at least 6 or 7 could be considered elite. And When it comes to forwards there's even more. I don't think the term elite should ever be pigeon-holes into one specific number. Personally I consider D and Z very elite, Kronwall no. Very proficient, but not a game-changer.
