Which LBs to start?

I need to pick 4 LBs to start this weekend. I'm in a 12-team dynasty PPR, IDP league. Tackles and passes defensed are worth 1.5 pts and assists are .5 points. Sacks, forced fumbles and fumble recoveries are worth 3 points. INTs are worth 5 points.

Woodley vs. Ravens
Tulloch vs. Broncos
Siler vs. Cardinals (has been my top scoring LB so far besides Greenway)
Rivers @ Browns
Bradley vs. Redskins

Thanks for the help!

I'd start:

Woodley
Tulloch
Rivers
Bradley

The only reason why I wouldn't start Siler is because Stephen Cooper practiced this week and is likely to return to his starting role with Siler heading back to more of a rotational role.
