He's been pigeonholed as the common denominator for everything bad that happens on the ice. Nobody is sure how it started, my guess is that an error that somebody made in the past was compounded by Holl making the wrong read, which ended up in the Leafs net. A goal that gave the opponent a late lead that turned into a loss. The broadcast director had camera 3 take a long lingering look at Holl head down in shame, while anger and disgust played all over his face. During that shot O'Neil or Craig Simpleton prattled on about, missed opportunities, poor positioning or poor coaching, pining it on Holl
Since that day it's just gotten worse for Holl with disparaging remark building on the last disparaging remark, until nothing else could ever be true about the player.
In Hollywood when this stuff happens to somebody and suddenly the knives come out and a career is suddenly in jeopardy, the person affected hires a great publicist, who's job it is to rehabilitate the person's image. So a few photos of the person feeding the whales, petting the lions on the savanna or some such, and boom Nick Cage gets his career back.
This is why Holl needs a really good publicist because his underlying numbers which cumulatively show him to be a highly competent defender, yet nobody seems to want to believe them because they belong to Justin Holl. A recent article that breaks down these numbers recently appeared on Sportsnet written by Justin Bourne
That all said and exhaustively written by me on my goddam phone is not saying Holl is perfect, nor an allstar, but what he isn't is the bumbling fool some folks seem to want to make him out be.
I hope this has provided you with some clarity.
