From what I noticed at the game last night:
Gonchar kept screening Fleury instead of boxing out opposing players. I'm pretty sure the first goal against even bounced off Gonchar to deflect into the net... So that was bad.
On the power-play, though, man, he was a sight to see. Excellent anticipation of where the puck would be so he was able to keep the puck in the zone more, and his ability to move the puck to a teammate's stick (and not to an opponents') was still as good as ever.
As others have said, I'd rather the team hired him as some sort of power play consultant instead of as a defenseman. Failing that, if they could unload Scuderi, keep Gonchar as a 7th/8th defensemen, and only dress him when the power play needs a boost... and dress 7 D on those nights so that Gonchar only needs to come off the bench when they have the man-advantage. Let's just say that I'd prefer he was signed solely for an off-ice role. Vastly prefer it.
