I'd go with Smith...
I think most "poolies" now have heard of Atkinson, plus he's in the most likely position to succeed in Columbus, where he should see some top-6 time which could generate more trade value...
With Smith and Wilson they're always going to be stuck behind the "big names" of Fisher, Erat, Hornqvist, Legwand and Kostitsyn. Also Trotz has never produced high point producers, his system doesn't really allow for it. So I would be more inclined to drop one of the Preds than Atkinson... I've given the edge to Wilson because he's had a few more years of NHL experience under his belt, and he did average more ice-time (16:07 and 2:19) than Smith (14:11 and 2:08).
My 2 cents.
