I would be supremely dissapointed if Larsson busts b/c of Stevens. If Sal can be serviceable, they can give Larsson softer minutes.
Dwayne needs to be in for someone because he can clearly handle tough minutes.
The problem with young defensemen is that unless you're extremely lucky, you have to let them suck. And we haven't been willing to do that. You learn through sucking. If you give a guy 320 over 4 seasons and he's still making the same mistakes, then maybe you can start to think they suck because they suck. But not the way they use Larsson.
