Yes he is a starting LB for Washington, Right Outside LB to be exact.
The reason Andre carries the DL/LB tag is because the Skins have just switched to a 3-4 Base D this year after running a 4-3 all of last year. It will be interesting to see tho as they may end up doing a bit of a rotation between the 3-4 and 4-3, because in a 3-4 Haynesworth would have to play DE which just doesn't work (if he plays) whereas in the 4-3 Carter would drop down to the DE slot.
Odds are tho they stick with the 3-4 with Albert's jerk-offedness, and because Carter can play either position and Orakpo is better fitted as an OLB.
A big thanks to deluxe_247 for the sweet sig!
