Because there are no WR2 or WR3 that are a significant upgrade over what we have.
Patterson, Allen, and possibly Austin (as a slot, think Smith and Welker) could all be number one's.
I don't think that us as football forum geniuses can say with all surety that Barden would not be a significant upgrade over what we have (like we have so much). Anyway, like I alluded to, Patterson, Allen and Austin will be gone before we pick in round 2, so if we don't pull the trigger, we aren't getting a WR1 from the draft unless we get lucky (much like we did with 89).
Easiest way to see who is right against who is wrong is go directly off of team's depth charts, not based off of opinion. So let's take a look shall we...
Julio Jones, Sidney Rice, Antonio Brown, Victor Cruz, Justin Blackmon, and Jeremy Maclin are all listed as one's based on teams depth chart's.
Well, since you are more concerned with being right, on a technicality, let me tell you that you are absolutely correct. You deserve a cookie. But... then let's take the earlier list and take the ones that apparently aren't technically listed as WR1s and add, Roddy White, Golden Tate, Mike Wallace, Hakeem Nicks, Cecil Shorts, and Desean Jackson. I suppose you think that LaFell can currently take his place among that number...?
Come on, dude.
