So I assume you'd trade Chara or Weber for Karlsson?
You realize that Chara won a Norris over Mike Green right, and is the only one of those three to win the cup?
There is a spectrum of toughness and a spectrum of talent, these things aren't black and white. You don't "have" toughness or skill, there are varying levels.
I know there are varying levels.
One of the posters said that we have to trade one of Gardiner or Rielly because they are soft. To that I'd say...Komisarek is a tough SOB but he sucks, Schenn is a tough D but his skating is terrible and fast smooth skaters like Kessel, Rielly and Gardiner could run circles around him.
A) Rielly isn't soft, he just isn't a hitter or an intimidator but he fights for the puck.
B) Gardiner is soft but has anyone seen the moves this guy can pull off against NHL defenses? He's easily the best player for the Marlies right now. He's going to run the PP this year if the lockout ends.
Chara is Chara...he's a bit of everything. Great offense, amazing D and intimidation factor.
Shea Weber's "toughness" gets overrated. Nobody is particularly scared of playing against the guy, he's a great D, that has a booming accurate shot and plays decent D. He's a smarter version of Dion Phaneuf.
Karlsson is soft, but he doesn't have to hit players through the boards to help his team win. He is orders of magnitude better than Mike Green.
Karlsson is similar to an NFL QB, the entire Ottawa offense runs through him. When he's on the ice, everyone has a change to put up points because he is elusive, hard to get the puck from and has great vision.
Ottawa was supposed to be a basement team because of inconsistent goaltending, bad D and lack of top six forwards. Karlsson is a big reason why they made the playoffs.
If he can put up ~80 points right now, there is no telling what he can do in the future. I think he's staying near PPG pace for a few years.

Also Chara winning the Cup has no barring to anything. This isn't the NFL or the NBA where we compare players by the number of rings they have.
Brett Lebda has a ring, and he isn't better than 99% of the defenseman in the league. Chara plays on a better team, he makes the team better but there are other players that do the same.
