We have our serviceable slot receiver already. His name is Zay Jones. We are a top flight WR away from having a decent corp. That is dependant of course on whether or not Foster can become a solid second option on the outside, which I think he can, but Zay can do damage when/ if used properly. Imagine a Julio Jones type, Foster, and Zay working slot. With a gadget/ speedster type for a 4 wide set. Add a good TE and we're good imo.
I'll hang up and listen to your thoughts now?
