Let me preface this by saying that, obviously, the Rams have chosen their course (and I think and hope, the player they felt was the best player overall, not just a scheme fit guy) and naturally, I hope it works out. I'm not even going to call the choice they made wrong as I don't believe there was a wrong choice between our top 3 options.
That said, I don't think our WRs are bad at all. My thought was merely that having a real #1 would draw coverage away from other WRs and make them all better. Quick, Bailey or Britt MAY step up into that level, but I'm kind of feeling like it will be a pleasant surprise if that happens. I also worry that in a run first offense, it'll be hard for Sam to look like a #1 overall pick.
As others have pointed out, we don't necessarily NEED a #1 to succeed, and outside of that lack of a #1, I like our WRs. If no one steps up, I can see it being an offseason priority next year. Hopefully we won't need another tackle then.
