I think he's a good fourth receiver, but being a part of the top three is a bit too high for him. He's shined in the preseason, but he should because he's got years of experience and he's going against backups primarily. The good thing is both him and Wilson seem to be able to contribute on a few plays per game and that's helpful with teams focusing on stopping Cooper, Lamb and Gallup.
Next year, when Gallup leaves in FA (or we cut Cooper to keep Gallup instead), we'll be looking for a third receiver, but I think it's a pretty big drop-off if we turn to either Brown or Wilson to fill that role. I don't think either can get consistent separation from No. 2 corners or even top nickel corners. When they are going against weak nickels or No. 4 corners, then the matchup favors them.
