Opportunities to add superstar pass rushers don't come around often in the NFL, but when they do, you've got to strike when the iron is hot. The Chicago Bears tried a few years back by making a blockbuster deal for Khalil Mack, because a player like that becoming available simply doesn't happen that often while they're in their prime.
The Buffalo Bills might have a chance to take advantage of the incompetence of the Dallas Cowboys, who are dealing with a major contract issue surrounding star pass rusher Micah Parsons. Things have soured to the point that Parsons is considering severing ties with the organization completely, and possibly requesting a trade away.
