This entire team has horrible high danger chance differential, heck freaking Draisaitl himself hovers at like 45%. The only players above 50% are McDavid, Hyman, Puljujarvi, McLeod, Nurse, and Bouchard. Yet Broberg's on ice save percentage is comfortably lower than all of the other players hovering around the same 40% high danger chance differential. The only player even in the same stratosphere as Broberg in terms of of poor puck luck on the Oilers is Derek Ryan at 0.843 OISV% and 88 PDO who also while not good so far this year is nowhere near "-13" levels of bad.
You could just blame it all on luck but thats not entirely what PDO is.
Also not all high danger chances are made even. Like a high danger chance from McDavid is much riskier than say a high danger chance from Derek Ryan.
They don't track varying levels of high danger chances. Heck, lets just ignore the actual goal numbers and PDO then.
Broberg has the third worst xGF% on the team for defense behind Russell and Koekkoek.
He shockingly has the 3 lowest rate of scoring chances but has the 2nd highest High danger chance rates, just behind Koekkoek.
You could blame Russell for that but Russell actually allows the 4th lowest high danger chances so, really, can't blame him for that.
He also has the 2nd lowest High danger chances for rates.
He has both the worst on ice s% and the worst on ice shooting%. You can say he is just really lucky but I mean....no?
Looking deeper at the numbers when he is on the ice he is not helping to produce high danger chances while allowing way to many.
Which is a clear indicator why his PDO is so low. Yes Broberg may not be -8 bad but he has been in the Koekkoek, Russell realm of defenders since he has been up and thats not a good sign
