p/u kerrigan & drop a LB?

Hi Guru, he's on the waiver wire, dropped the morning before his 4 sacks....do you suggest grabbing him (5 pts for sacks, 1.35 for solos)?
my Lbs are: Collins, Cushing, CJ Mosley, Shazier, Lemur, Kendricks.   If I do, Lemur seems like the choice, though Roach is out there too and I kinda like him   thanks

Given the slant towards big plays and your depth at linebacker I'd roster Kerrigan and try and capitalize on his upside in good pass rushing matchups. Lamur could have nice value this week though if Burfict sits.
