The final player is by far the one that every team in the NFL should be interested in if he becomes available in defensive tackle Aaron Donald. He is arguably the best defensive player in the entire NFL even at 32 years old.
Donald's resume speaks for itself as a three-time Defensive Player of the Year, seven-time first-team All-Pro, and nine-time Pro Bowler. He has 103 career sacks and would join a defensive tackle position that already includes Ed Oliver and DaQuan Jones.
The Buffalo Bills already have two defensive linemen from the Rams' Super Bowl team with Von Miller and Leonard Floyd. If they could also add Aaron Donald, alongside Oliver and Greg Rousseau, it would be a nightmare for opposing quarterbacks and offensive coordinators in how they could block this much up front.
Most of these trades probably wouldn't happen until midseason when teams decide if they are going to make a push for the playoffs or try to add some draft capital. If the Buffalo Bills get off to a fast start and need that one final piece, these are five players that would make a great deal of sense.
