or we trade them both and sign a Reimer or Raanta or Talbot or something as a backup/tandem guy.
Honestly, I think keeping Sammy around to see if this is a breakout is the play. He was a very highly regarded goalie prospect who sucked in Washington but had a very good year last year. There's some contract scenarios (including just taking his 1 yr arby award...probably in the 3-4 million range) that are fine. If he does it two years in a row ("it" being 40+ games of .915+ hockey) then paying him 5x5 or something isn't the worst idea in the world in that scenario.
Safer play might just be to sign him to a 2-3 yr deal now (3/12 or similar) and if everything comes up Millhouse with Woll & Hildeby, he's a good trade piece as he will almost definitely get blown tremendously by the media.
