There's more to a player than points, if you had to win one game would you take him over any of those players with the possible exception of a well past his prime Arnott?
There are lots of players people would take over Gagner.
But the NHL is not a fantasy league, and the real disconnect in the arguement is that the Oilers somehow have the option of replacing Gagner with someone bigger/better when they spent the better part of a decade fruitlessly trying to obtain centers anywhere as good as Gagner in the first place. Endless fantasy trades for unavaliable players, citing teams with 2 first line centers as a realistic model, and ideas about drafting 18 year old players and slotting them in as effective 2nd line centers the very next year all amount to the same thing - wishful thinking.
I'm starting to think Arcobello might be a better 2C than Gagner.
I know it sounds a little crazy but he seems to have excellent chemistry with both Schultz (especially) and Eberle. He also seems to have better on-ice vision than Gagner. I'd be willing to at least try him out in the NHL.
So a smaller, older minor league player who has never played a minute of NHL hockey, is somehow a potential replacement for Gagner?
