Edmonton is 4th in CF%, 3rd in XGF%, 6th in SCF%, and 2nd in SCF%.
Edmonton needs a defensive upgrade on the right side, but up until three games ago, the shooters had scored 13 goals below expected and the goalies had allowed 15 goals above expected. That's a killer combination.
Now, the scoring has woken up, but we still have some issues in net and Skinner has played 13 of the last 15 and looks wiped sometimes. I honestly don't think Edmonton needs anything world breaking though. They need NHL average goaltending.
