The Patriots don't have a major need at wide receiver, but that doesn't mean there isn't room for improvement.
It's become an annual tradition to link the Patriots with more offensive weapons. Whether it's an aging veteran (is Larry Fitzgerald/Andre Johnson available?!) or a deep threat (Mike Wallace/DeSean Jackson would be great fits!), the Patriots are always assumed to be a potential landing spot.
The reasoning behind the argument is generally the same. Tom Brady needs help in his final years and adding one more player would make the offense unstoppable!
