​ESPN currently ranks the Buffalo Bills as having the fourth-best roster in the NFL as they head into 2026. Yet among league peers, a persistent concern continues to surface: who is the guy who can change games on defense? On offense, the answer is straightforward. Josh Allen stands among the league’s elite superstars. On defense, however, the issue carries far greater weight and may be the most significant hurdle for a team that still eyes a realistic Super Bowl run.
NFL insider Jason La Canfora recently conveyed that several league executives believe Buffalo still lacks a true dominant edge rusher who can consistently take over games at the most critical moments. His suggested remedy? Pursue Arizona Cardinals defensive end Josh Sweat. In conversations with an anonymous NFL general manager, La Canfora offered a blunt appraisal of the Bills’ defense: “They still don’t have a guy, and it’s hard to get where they want to go without one.” He also noted that Buffalo isn’t expected to bring back free-agent veteran Von Miller, and he viewed the one-year stint with Joey Bosa as insufficient. La Canfora believes Sweat could be the missing element. “Somebody is going to pry Josh Sweat out of Arizona. He doesn’t want to be there, and they aren’t close to winning.”
Buffalo has invested heavily along the defensive line in recent seasons, yet their pass rush largely operates as a committee rather than being driven by a true game-changing edge defender. As the 2026 season approaches, the Bills boast plenty of intriguing talent. Greg Rousseau has evolved into one of the league’s better all-around defensive ends, even if he hasn’t consistently posted double-digit sack totals. There is real intrigue about what new defensive coordinator Jim Leonhard’s system will unlock in Rousseau’s game.
Buffalo also added veteran Bradley Chubb and drafted T.J. Parker in the second round of the 2026 NFL draft. Michael Hoecht will bolster the rotation, though questions about his health linger as he recovers from an Achilles injury. That group should be productive, but the lingering question remains: can it be truly dominant?
History suggests that many championship teams eventually rely on one edge rusher who can win obvious passing downs almost on his own. Think Myles Garrett, T.J. Watt, Nick Bosa, Maxx Crosby, Trey Hendrickson, or even Sweat during the Philadelphia Eagles’ title run. Those players are the ones coaches design plays around each week. Buffalo does not currently have that kind of single-game changer on their defensive front.
It’s a tough stance to dispute entirely. Sweat checks almost every box. At 29, he has tallied 20 sacks over the past two seasons and posted career-best pressure rates from the edge. He remains in his prime and has demonstrated a consistent ability to reach the quarterback from the outside. Unlike many veteran pass-rush veterans who become available, Sweat wouldn’t merely be a situational upgrade; he would represent a meaningful, ongoing upgrade to Buffalo’s defense that could alter how their entire front is schemed and deployed. The question, of course, is whether the Bills can land Sweat and integrate him into a defense that is still finding its exact identity under Leonhard, with an eye on maximizing a potential championship window.
