It's really simple if Chris Borland is on your waiver wire HE IS A MUST ADD! Whether you start 1 IDP or 10 IDP, pick him up! I play in a league with a QB, RB, RB, WR, WR, Flex, TE, LB, DB, DL, DEF and K. I picked him up and he scored more then ALL MY OFFENSIVE players! He was my top scorer and the best part is my offensive players didn't have a bad week.
So here we go except for Chris Borland here are the LB's you should be looking at
Chad Greenway (MIN): He has been on this list a few times, yet he is only owned in 20% of ESPN leagues. He is a LB1 and should be started as such
Avery Williamson (TEN): This rookie is starting to make a real impact in Tennessee add him as a solid LB2, he has 28 tackles and 3 sacks in his last 3 games! that is very high upside
Jameel McLain (NYG): He took over from Jon Beason and has shined in that time. In the past two weeks he has 26 tackles and a forced fumble. I wouldn't expect too many big plays out of him but he will get you the tackles
Christian Kirksey & Craig Robertson (CLE): Karlos Dansby is out at least one month. Kirskey has the higher upside here, however to completly count out Craig Robertson
Keep an eye out for Devonn Kennard (NYG)
AT DL: If you own J.J.Watt I am one of the people who hate you. 2 offensive TD's this season as a TE!
Alex Okafor (ARZ): He could be listed as a LB in your league as he is a an outside linebacker. Has been consistent for Arizona and is a potentialy decent add this week DL2/3 or LB4/5 depending what he is listed as in your league.
Aaron Donald (STL): Part of the reasons the St.Louis Rams are playing better is this rookie. Has been a dominant force and if you start defensive tackles he is a DT2.
Robert Ayers (NYG): 3 sacks in the past 3 weeks. I'm buying! Cowboys in week 12 are not the best matchup but I am still ranking him as a DL2/3
Ron Parker (KC): He was on this list last week. With Eric Berry back he moved back to this CB role however he now is staying on the fields for those tackles and had a great game vs. The Seahawks! Start him as DB2 with DB1 potential.
