It's hard to gauge where the WRs rank when you have a QB that doesn't throw to them. Matthews and Clay have been proven to be productive pass catchers, and Shady has got to be one the top 5 pass catching RB's. IMO they are comparable to the Chargers, Ravens, Dolphins, Titans, Jax, Houston, Indy, Carolina, Washington, Philly, Detroit, Chicago, Minnesota, Rams, Seattle, Arizona. There are only a few teams that are far ahead with talent at pass catchers, I feel like. You need a sufficient passer to showcase your talent. Even in limited preseason series, you got to see a small glimpse of what kind of catches Zay could make, with NP giving him a chance to make plays. Your WRs can only be as good as your QB lets them.
