McDavid still gave up a ton of goals against. 17 at 5v5 in 16 games or 3.6 GA/60. And it wasn’t all on goaltending since his xGA/60 was 3.06, and he gave up a ton of shots (39.38 SA/60!). He also gave up more goals against per 60 than when he was on the bench (3.6 vs 3.29), so saying “the majority of goals against were when he was on the bench” is pretty misleading. Yea, 60 % of the goals against were with him on the bench, but that’s because he was on the bench for over 60% of the team’s total 5v5 ice time.
Now, he scored an absurd rate 5v5 (4.45 P/60 and 21 points in 16 games), and the team scored an even more absurd rate (6.56 P/60) when he was on the ice, which meant his GF% was still amazing (31GF/17GA or 64.6%). It deserves to be included in this list, but his production also needs context. There was a lot of run and gun games, particularly in the Calgary series as well as some score effects at play.
