I think we should accept that a true #1 WR is not in the cards for us. And probably won't be until some date in the far future when we get to pick a lot earlier with our first selection.
Rams don't have the money for a #1 WR in FA either. It's not gonna happen. It's not even a consideration in fact IMO barring a weird situation like we had with Faulk which comes up once in a blue moon.
And that's ok. If they keep Woody & Kupp and restructure then Jefferson will probably compete with a rook in the slot and that's something we can get well into every draft. IMO focus on the waterbugs this year in the draft. That's the direction the Rams will go if they want more speed in this WR corps. They don't have much choice.
