Bill did say that WW blocked JE from playing more at WR but you are 100% correct. Any rookie WR will not come in and produce like Jules is now Year 1.
We hate to bring this up but the most recent rookie success story (for Year 1) is Dropson. He played 12 games with a season shortened by a foot injury. He averaged 46 snaps, 3 catches and 43 yards a game. Cumulatively he had 37/510/4TDs. I think everyone on this board would be happy if that is what a rookie did in this offense next year as a WR3.
With that said obviously he was a bust.
