I would be willing to bet that if we don't sign a remaining UFA forward or pull off a trade before the season begins, Tedenby will be on the squad come opening day. I dont think any of the other guys you mentioned will be. I also don't see Harrold playing a lot of wing after his defensive performance during the playoffs unless it was an injury situation.
Yeah I think Hoeffel is too young and Whitney is too small. Darcy Zajac might get a chance just to entice Travis to sign a long term deal. But I'm not sure about Tedenby. He was end down to Albany because of his lazy play and he didn't do anything to raise his stock while down there. He might get some playing time during the preseason but I'm not gonna hold my breath that he makes the team.
If we are able to trade any combination of our starting defenders (Tallinder, Greene, Volchenkov) with one of our defensive prospect (Urbom, Burlon, Gelinas) with maybe a 2nd or 3rd or even Tedenby, we might be able to land Gagner or Hemsky from Edmonton. Maybe throw in Omark somehow. I just don't see us landing anything of great value by trade. I'd rather go for Gagner and Omark than Hemsky if possible. Hemsky is too old and fragile for us to be parting with anything significant.
