Andersson has been useless anytime he's not playing with speedy wingers like Nyquist/Tatar.
Bert's a fourth liner PP specialist. I'm sick of him dragging down our top 6
Miller-Andersson-Bertuzzi big bodies that can grind teams down. Pretty slow though. Bert needs to adapt to this role and be effective or he can retire. He's a good guy to have on the roster that would be a fun fourth line
Bertuzzi has been useless anytime he hasn't played with Datsyuk+Z.
Those two aren't going to grind anyone down because they'll be two-three steps behind everyone all the time.
