I don’t think he has been. Now he’s very young. So he can definitely improve.
Duchene? In Colorado? Where he was infamously disgruntled?
if Greig does blow up then don’t know if we can even afford him and pinto
Was Duchene disgruntled because he was playing wing or because they were losing?
Giroux was listed as a winger until he was 25, then started playing wing again in Philly at 29.
Centers playing wing isn't as uncommon as you are suggesting.
If Greig does blow up and we can't afford him, deal with it then, his value will be higher and we'll get more for him.
