speculating on what level of discomfort an athlete is experiencing or what level they should play through is gross. you can't say that sid should have played better. all you can say is that he played poorly.
my only gripe is that he was really lousy on the power play. to the extent that it would have been better without him on it. if the team knew this is the best we were going to get out of sid, i wish they would have strategized a work around. additionally, they shouldn't have butchered an effective 2nd line in order to elevate a hobbled player.
