Do you think he’s the thirtieth best ceterman
Is it really that outlandish?
I think all of the following centers are better: McDavid, Crosby, Malkin, Kopitar, MacKinnon, Tavares, Kuznetsov, Backstrom, Bergeron, Barkov, Getzlaf, Stamkos, Scheifele, Seguin, Carter, Toews, Draisaitl, Matthews, Thornton, Staal, Eichel, Point and Monahan. That's 23 above him right there. Not to mention young guys poised to pass him like William Karlsson, Matt Barzal [probably already better], and Vincent Trocheck.
I rank him in a tier with guys like Johansen, Couture, O'Reilly, Schenn.
So I guess Duchene is somewhere in the 25-35 range depending on how high or low you are on the guy. If you are a serious contending team then Duchene is your second, or in some cases [Pittsburgh, Tampa, Washington, San Jose, LA] third center.
Good player, not great. Not a franchise piece.
