I think it's very accurate and what makes you say it's biased? And he never said (or even implied) that CBJ is an offensive team, perhaps you should give his post another read.
Before he was given the "mod" status I've had plenty of debates with him; I know where he stands when it comes to dubas and analytics.
Lets look at the result from the entire season then -> do you recall pulling your hair out pre-covid when this team played in it's own zone? I do. This isn't just the CBJ series it has been like that for a while now.
CBJ series is just the tip of the ice-berg. Everytime we had the puck at the point in the offensive zone we were covered or the lanes were closed so shots were blocked;
Werenski, Jones, Savard they had free lanes taking shots from point; the first goal last night, for example, why the hell did Werenski have so much time and space to float a shot; we left the points open and played chicken in the D-zone.
Freddy had to cheat because he had absolutely ZERO faith in the team's defensive ability especially in their own zone; Korpisalo on the other hand only had to be aware of few lanes where he knew shots might come; other than that leafs were mostly kept to the outside.
CBJ is opportunistic they wait for you to make mistake and then pounce on it; and leafs make plenty of defensively boneheaded plays
