Vince Williams Steelers LB (1 Viewer)

I have a question about Steelers linebacker Vince Williams . I was watching the game last week and I noticed that he was not out on the field in a lot of passing situations. Looking ahead at this match up with New England. They like to throw to the running back‘s quite a bit out of the backfield. Does that create more or less tackle opportunities for a linebacker like Williams? Is he a everydown linebacker or does he come out on obvious passing situations 

Williams played 83% of the defensive snaps in Week 14, 84% in W13, and 78% in W12. So while it does seem there's been an uptick in his usage since Shazier went down, he's still coming off the the field in certain subpackages.
