But it doesn't matter as long as the good>>>the bad. That's why Buff was an all star D despite being defensively 'meh". Same with Erik Karlsson, who may have been better offensively but is worse than Pionk his own zone. Didn't stop him from winning an award or two.
Here is how defensively meh Pionk has been this year, compared to a random $8M #1-2 D on the Rangers:
Pionk: (36 points, 14th in NHL among D) 50.9 CF%, +3.2 CF% Rel, 4th on his team in +/-
$8M-dollar man: (23 points, 49th in NHL D scoring) 44 CF%, -3.5 Rel% CF, 23rd on his team in +/-
