Trubisky is Buffalo's backup to Allen after beating out White; ranked 28th among NFL backups by FanDuel, signaling limited fantasy upside unless Allen is sidelined.

Trubisky won the backup QB job again, beating out Mike White. His retention adds stability behind Allen and signals a measured, game-manager approach in relief roles. For fantasy, this solidifies a safe hold in two-QB and superflex leagues, with upside if Allen misses time, especially in game-script heavy scenarios.

Trubisky led Buffalo’s air attack in the preseason, delivering a 58-yard strike to Shavers and showing timing with a growing receiving corps. His connection with downfield targets and comfort within the Bills’ offense add a reliable floor to the depth chart and influence on WR values across the room as final cuts approach.
