I doubt that Zus is back. He might be, but I would think that he is likely not re-signed. If he is re-signed, I still do not see him on the second line. He would more likely be the fourth line center, or an occasional player. Still not too sure what the lines will look like. I really think that you will see Saad on one of the top two lines, the kid is just too damn good. Also, I am not so sure that Hossa will be ready come the start of the next season if he truly does need surgery. Not that it would be a huge deal if he was to sit the first half of the season, as long as he is good to go for the playoffs.
With Q's line blender in action, you never know what you will get from night to night anyway.
Back on topic, I really hope that the Hawks can get something done with Bickell. He seemed to finally have something click this season. I do not know if it was just finally figuring it all out, or if it was a contract year deal. I really want to believe it was the former, because I really like the guy.
