Of course teams are calling about Roberts Woods (and Jefferson, I suspect) after the Robinson signing. It is natural to assume that the Rams could now be ready to part with a big-name WR after the Robinson acquisition. Even many Rams fans suspected as much.
Personally, I do not suspect that the team is looking to move Woods. I look at Robinson as more of: (1) an insurance policy, with Woods (and OBJ, if he returns) coming off an ACL injury at a somewhat older age; (2) a big body, physical, contested catch specialist that should mesh with Stafford and is something the team currently lacks; (3) McVay always wanting more and more weapons, and in particular, at least 3 potent WRs on the field at all times. So I suspect the Rams are not looking to move Woods.
Woods and Robinson are very different WRs. Woods' role in this offence is very unique, and I don't see anyone that can fully replicate it.
But like almost any other player in the NFL, if the right offer is presented, it could make sense to move Woods. There are some exceptions where you pretty much could never move the guy (AD, KUPP, Mahomes). But if teams are calling, maybe it ends up leading to something that was not originally in the plans. We'll see.
