I just hold Sid to the standard Sid has set for himself. I did the same thing with Geno a couple years ago and I can still remember the game against Nashville where he finally decided to turn it on and get back to being Geno.
Like others have said… with the face-offs down and the goal totals down, combined with the offseason news about his wrist, you have to believe his wrist is effecting him. He took a chance by opting out of surgery, and as more and more time passes, its looking like that probably wasn't the best decision.
