The Buffalo Bills (2-0) return home to Highmark Stadium on Sunday, September 27 (1:00 PM ET, FOX) looking to remain undefeated against the winless Los Angeles Chargers (0-2), but Joe Brady’s offense faces major late-week availability questions. D.J. Moore and Keon Coleman are listed as questionable and considered true coin flip gametime decisions. Moore, who proved vital in Week 1 before exiting early against Detroit, will require a pregame injection to suit up, while Coleman returned to practice Friday on a limited basis. If either receiver sits, expect Khalil Shakir and former Charger Josh Palmer to take on expanded perimeter workloads alongside fourth-round rookie Skyler Bell.
Regardless of receiver availability, Buffalo will continue heavy reliance on its elite tight ends. The Bills run three-TE sets at the second-highest rate in the NFL, with Kincaid asserting himself as one of the league’s most efficient pass-catching weapons (225 receiving yards through two games). To pinpoint where the premier wagering leverage resides for Sunday’s AFC matchup, we matched dual machine-learning simulation models against real-time pick ‘em multipliers on Underdog Fantasy (code CUSE).
