I actually don't think any of these receivers are getting traded.

Here's why:

Hurns is the best slot receiver on the roster at the moment. Westbrook has been playing outside and hasn't learned the route tree at the slot yet. He may eventually fill that role, but it's doubtful in 2017.

While many are ready to slide Westbrook or Cole into Lee's spot and ship Lee out the door, he's still the only proven receiver on the roster ready to play that spot opposite Robinson.
Westbrook and Cole have not shown yet that they can beat the jam from press coverage against NFL starters. And Marrone has stated clearly the importance of that trait in his receiving corps. It's why he started Westbrook working the outside spots instead of in the slot.

The team likely values Lee and Hurns more than what they could get for either of them right now unless someone is offering up a stud left guard. (doubtful) No one's giving us an answer at QB for one of these guys unless we package a high pick with them.
If they were going to do that, I think they'd have done it sooner. Week four of the preseason is a crap time to be teaching a new QB the playbook.
