I've often wondered why the Sabres don't try moving 57 to the wing, he can skate, he can handle the puck...let him unleash that shot from 20 feet from the goal instead of 50...lets see what happens.
Let Myers bang away in front of the net for a few nights to force him to play more physical, see how Chara does it up close and personal, that way when he does move back to the blue line he clears the net a little more forcefully.
Nows the perfect opportunity.
And before you write this idea off, might I point out that Phil Housley put together a pretty nice career under the same circumstance.
He's more effective as a defenseman than he'd ever be as a forward. Not that they're comparable players, but people always say this about Karlsson which is madness, because his value is being able to rush up the ice from the backend where he can see everything, while he'd get dominated physically as a forward. Myers is obviously bigger and stronger but he's still better suited for swooping into the play with a few long strides than he is playing down low. He's not that skilled with the puck to where I think he'd be very successful down low where he has less space to work with, especially being so long. Instead he can find space from his vantage point and cause havoc.
Part of why people always say Karlsson should move to forward is because they believe he's not good defensively, which is nonsense. Myers too is effective defensively, if not perfect. He uses his tremendous combination of reach and skating to keep from getting beat outside, he's become increasingly better at muscling guys on the boards and in front of the net; check the roughing, boarding, etc penalties he gets now, many of which are unfair calls that are simply due to his leverage advantage overpowering others, as happens to Chara. His biggest drawback is that his hockey IQ is average at best, which might get masked a bit as a winger, but then you're really neutering his biggest advantages offensively which are his ability to rush up ice and his ability to swoop in from the point (we call that "going condor").
