Thank goodness we aren't Toronto. Can you imagine being a capped out, 1 round playoff team, with no realistic ways to upgrade the roster?
They will literally have negative cap space after they sign Marner to a big deal this coming offseason. And that's before they re-sign Kapanen and Johnsson to likely fairly significant raises.
Yeah, they can trade Connor Brown and/or Hyman probably to become cap compliant (although the Kapanen/Johnsson deals may eat into any savings they get by trading these players away). But that doesn't make them a better team and they are already losing Gardiner this offseason and replacing him with no one.
Good luck!
