A Super Bowl caliber team needs more depth than the Bills currently have
Depth and the ability to replace players who are injured is a key part of building a championship caliber roster. No team in the NFL is going to get through a season without major injuries, so to enter the season with any unit on the roster already thin is a huge risk. Beyond Miller and Gregory Rousseau the Bills only have Boogie Basham and A.J. Epinesa on their roster.
A team with Super Bowl aspirations needs more depth than the Bills currently have, and the Bills should not count on Basham and Epinesa taking huge steps forward at this point in their careers and becoming impact players.
Unfortunately, there are only a few real options available for Buffalo, such as the Bills 2016 first-round pick Shaq Lawson who is currently a free agent. Prior to the 2022 season, the Bills brought Lawson back on a one-year deal, and it makes a lot of sense to do the same this off-season.
Despite some good moments in 2023, he profiles as a back-up and depth piece as he has never played up to his first-round selection in his years with Buffalo, Miami Houston and the New York Jets. As a backup and rotational piece who is familiar with the Bills coaches and defensive system, he makes a lot of sense to bring back.
Beyond Lawson, there are few options this late in free agency. This puts the Bills in the unenviable position of either needing to trade for a defensive end or rely on a rookie, which the Bills have been reluctant to do in recent years.
