It appears that Dougie Hamilton, the headliner of the 2021 free-agent market, is not the Flyers’ top priority.
In the latest edition of 31 Thoughts, Elliotte Friedman reports that the Flyers’ defensive targets seem to be elsewhere. He later expands on this point:
15. Philadelphia’s got a lot of balls in the air. I figured they’d be in on Hamilton, but, as mentioned above, he doesn’t appears to be their top target. I’m speculating here, but my guesses would include Seth Jones and Matt Dumba (who GM Chuck Fletcher knows very well).
