I mean he couldn't have predicted that a global pandemic would have caused the salary cap to stay flat.
And using that cap space for Tyson Barrie or Pulju/Ennis/Kahun was worth it imo.
I don't miss him for a second. He's a puck hog that kills plays. He fits on a certain lineup lacking offensive skill but not on the Oilers. I didn't want to resign him even if the cap rose.
The cap space used on Barrie and replacements like JP/Ennis/Kahun made the team overall better. Finally the Oilers can breakout from the D! (and injecting the Condors D also helped)
