Swap him with Dahlin, who looks like he could use some AHL confidence work.
Seriously though, I think Samuelsson will be in the NHL as soon as he is back in playing shape. He is ready.
While I doubt there is anything imminent, I would bet GMKA is still actively working on further trades to build this roster. Joker, Dahlin, Bryson are the only defenseman on the current roster signed past this year. That makes Pysyk, Hagg, Miller, and Butcher all tradeable components anytime between now and the deadline. I could easily see them trading one or more of them to open a space for Samuelsson.
