Waiver Wire Pick-Martinez, Heeney, Orr, Whitehead, ZBrown, Foster

I play in a 12 team tackle heavy IDP league with 5 IDP starters. After the draft, the waiver wire is pretty thin. I have one bench spot that I need to fill for an IDP position with high upside. If I had to pick one one the waiver wire out of Martinez (GB), Heeney (OAK), Orr (Balt), Whitehead (Det), Zach Brown (Buf), Foster (Wash), who would who you suggest?

Many Thanks.

I would go with Martinez. The pack just released Barrington which makes it quick likely Martinez will be an every down player and produce nice stats.

Do you think that will remain when Ryan comes back from injury?

I do. The Pack like Martinez' coverage ability and his intellect in terms of defensive play-calling. I think he plays every down and Ryan could get replaced by Morgan Burnett at LB in subpackages.
