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
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.
