LB Waiver Help

Wilhoite, Perryman and Christian Jones are available on the wire.  We start 2 LB's and flex and are able to keep 1 LB at end of year.  Tackle/Assists (1) counted equally along with points for FF(4), Sacks(4), PD(2), Int(5) .  My current LB's are Keenan Robinson, Derrick Johnson, Mychal Kendricks and Kwon Alexander.  Would you make a move for short-term or long-term?

Wilhote, I mentioned him before this weeks games, hes locked in as the starter and racking up the tackles. Id probably go Wilhote long-term over Robinson, hes always been a solid tackler when hes started
