I personally think assigning random numbers to WRs is a bit meaningless. "This guy is not a 1, this guy is good, but he's a 3 at best." I just don't think any of it really matters.
I also would have preferred someone bigger, but if he plays like Steve Smith I couldn't care any less. I just think the way Love plays, a big body would help. He takes a lot of risk, he will throw into traffic deep, he will take a shot into double coverage...Watson really started to become that guy right before he got hurt.
But like I said, they need Golden to become their best WR, or maybe Reed takes the jump, but they need production out of him, and quickly. The group as it stands is not good enough. It's average; deep, but with average talent.
