Blocked shots is not a good thing to lead. That shows he's spending a lot of time without the puck in his defensive zone allowing the opponent shot opportunities.
I don't know about you, but when Crosby, Draisaitl, McDavid, etc are on the ice, I expect them to be generating offense sometimes.
It's just natural that those players will not always be pinned in their own zone.
If I constantly have a set of players facing that top level opponent, it's folly to not expect them to be on the ice for a bunch of shots against, even goal scoring chances, and heaven forbid - goals against.
I just hope that the group of players I have facing those kinds of opponents, can either hold their own or even spend more time in the opponent's end of the ice than in their own end.
Thankfully, Matthews and Marner do just that, so they have always been a net positive in that regard.
I suspect that players like Bergeron are on the ice for tons of shots against and scoring chances as well, based solely on the opponents they're asked to play against.
I'm too lazy to look that up
