4. Wide Receiver
This is another position I don't think the Bills need to focus on too much but getting someone like Terry McLaurin wouldn't be a bad thing. I wonder though with Khalil Shakir and Dalton Kincaid starting to contribute at high levels, I don't know that it would help the team out that much. That said, with Gabe Davis on a contract year, maybe the Bills play ahead and go ahead and make a move for a wide receiver, if they don't think they can get an extension done with Davis.
Other names that have been thrown around in potential deals are the Denver Broncos Jerry Jeudy and Courtland Sutton, as well as Deandre Hopkins and Devante Adams. Adams would definitely be a game-changer, but I don't know if his contract would work with Buffalo's current cap situation. As far as Jeudy and Sutton, I don't think either of these players is the receiver many believe them to be. However, maybe a change of scenery and an elite quarterback could change that thought.
