I think it's pretty obvious that EP re-aggravated his wrist injury a couple of weeks ago. Once he got the tape off in late January, he was back to ripping one-timers and getting results. For a while, he was the EP from earlier seasons.
Watch him on the PP now, he is getting dished the puck and he just gives it back to whoever passed it to him. That, or he does a pump fake and waits until the goalie is set before releasing a predictable shot. It must be his wrist causing him to not have confidence in releasing his one-timer.
For that reason, I'm going to give him a mulligan this season. I saw that he still had it for that brief window that his wrist was back to normal. He's obviously playing hurt.
