You might drop the Shark's an e-mail and let them know so they can re-position him from center to left wing.
I went with Marleau due to him being offensively better than Kesler (and Koivu, marginally), is still one of the fastest skaters in the league, is very solid/underrated defensively (i.e. 3rd in SH TOI/G for forwards on the 3rd best PK in the NHL) and is pretty much an iron man.
I'd rather have Backes of all of those so voted him. Atm some of the names are better than him but I think he's battling some groin injury that hampers he's play. Doesn't have the same jump as last season. Though he's getting up there in age too.
