When I read the title to the OP the first thing that came to mind was from a few years back when our d line got zero ol holding calls against them for 5 or more consecutive games.
But even with that said, the human error and inconsistency of calls seems to be at an all time high this year.
Honestly, it's just another reason we are so lucky to have Parsons. The refs know this stuff. They see him getting held but likely are scared to call it so often just as they are for the other dominant pass rushers of other teams.
It's almost like the NBA sometimes and the infamous make up call.
Like they try to intentially not call on one team but try to make up for it by not calling it on the other team later on as well.
So the dreaded, it all equals out in the end.
Even with all this though I usually end up agreeing with MarcusRock that we are no worse off than other teams.
Maybe instant replay on ref calls should be a consideration.
