On these boards, a player is only as good as they're playing at the moment, so the poll isn't surprising.
This contract isn't about money, it's about play style. If we're trying to turn the Rangers into the old Canucks, go ahead and trade him. There's no room in that system for a skilled grinder. It's setting a good player up to fail, and as far as being captain goes, puts his playstyle at odds with the rest of the team. See what Colorado would be willing to part with; team with alot of young talent, and Cally on a line with Lando or RoR sounds extremely appealing.
If we want to keep any trace of the best rangers team in nearly 20 years, you have to keep Callahan. He won the C on his jersey with heart and soul, taking the body and giving his up. Timely goals, non-stop effort, and insipiring play are all his calling card. If you want to keep that, you need to change the firepower on this team to more Cally/Stepan/Hags types. Players who get in deep, work below the circles, and gut out goals.
I think we should keep him, and try to adapt a more western style of play. Puck possession is a tough game to play, and we're not the Pens. I don't want to see them play like the Pens. I hate Pittsburgh.
Get younger. Get tougher. Get hungry. Keep the core, compliment them with youth. The energy is infectious, and a Callahan on his game is a true impact player.
