Sergei Shirokov looked out of pace and place in his first 3 NHL games, registering zero points and was a -4. There were times that I thought that if he just scored once that perhaps he'd start flying. Playing with the Moose will help him. I'll quote Mike from the comments thread in the post below:

He got sent down because the Moose have back to back games in the next few days whereas the Canucks don’t play again until Sunday night. He’ll more than likely be called back for Sunday but I doubt he’ll suit up after the win. I’d guess his next game is next Friday in Calgary.

I mostly agree with that, except that if the Canucks keep winning I wouldn't be changing anything until an injury occurs.
