Not sure if this was posted already but Sherman wrote a little op-ed:

As far as Crabtree being a top-20 NFL receiver, you’d have a hard time making that argument to me. There are a lot of receivers playing good ball out there, and Josh Gordon needed 14 games to produce almost double what Crabtree can do in a full season. And Gordon had Brandon Weeden, Brian Hoyer and Jason Campbell playing quarterback.
