Are they playing crappy defense??
I am not big on advanced stats... but they are second lowest team for SAT against at 1345. Ottawa is the highest at 1931. Not sure how to read the stat... but these are two of the worst 3 teams in goals against. It seems kinda weird that one team is at the top of the SAT against list and one is 2nd from the bottom. So you tell me if it is crappy D, or crappy goaltending in each of Ottawa and Philly.
Flyers are also top 10 in allowing the least number of shots. I usually equate brutal defense to allowing a lot of shots and a lot of scoring chances... but I am old school in a lot of things... maybe this is one of them.
