Malcolm Smith or Vincent Rey?

Malcolm Smith is probably the best LB available on our league's waiver wire.  I have Luke Kuechly (on IR - doesn't count toward my roster limit of 6), Telvin Smith, Khalil Mack, Keenan Robinson, Demario Davis, Jordan Hicks (thanks for the tip!), and Vincent Rey.  I'm wondering if I should secure Smith instead of probably Rey.  It would mean that I'd have two Raiders LBs, which is probably not advisable, but we start 3 LBs per week, and I want to keep the best 6 available on the roster.  Note that we get big points for big plays (sacks, INTs, etc.), along with regular tackle points.

Thanks for all the great advice over the years.  I really appreciate your insights.

I like Smith, the main reason is hes locked into his role all year, Rey is not, just a thought on Hicks, it's not given he starts and may become a rotational player when Kendricks comes back, he looked better than Ryans, so he might have taken the starting job but honestly its never a given.

Kendricks looks like he will play this week, if he does bench Hicks for the risk he ends up only getting rotational snaps

Thanks for the advice! I appreciate it.
