you don't need help with that for sure.
Last year, Bonino was every bit as equal to Duchene, I don't know how you could argue otherwise and given the icetime each got, I'd say he was easily better.
Is he as equally talented? No. Does he have the same skill level? No. But last year, he performed every bit on the same level.
Rare is the post where I defend Duchene, but...
Bonino was on a Stanley Cup winning team and played behind currently the best Center tandem in the league.
Duchene played on the worst team in the league. Possibly the worst team that has been in the NHL in 20 years. And that's coming from a long time Oiler fan. He had a terrible, terrible year. He still managed to get more points than Bonino. Are you really going to compare the two?
If you put Bonino in Duchene's position last year I bet he doesn't break 20 points. He'd crumble like he was made of graham crackers.
