Buffalo’s 38-0 setback at Chicago showcased depth over starters, not a season-long collapse. With most top players resting, the Bills used backups to gauge their Week 1 readiness and to gauge who can step up if injuries hit early.

Mitchell Trubisky opened as Buffalo’s Week 1 quarterback, while Mike White took the backup reps. White’s rough showing against Bears reserves could tilt the hierarchy toward Trubisky as the steadying presence behind Josh Allen, at least until the regular-season slate offers clearer snaps.

In the back end, safety depth drew scrutiny. Jordan Hancock flashed in flashes before a shoulder injury, and Damar Hamlin and Cole Bishop had rough moments. Those injury notes and performances matter for late-round safety targets and for monitoring how Buffalo will rotate behind starters.

The gassed second unit on defense and the broken run of tackling highlight depth concerns across the board. Buffalo’s ability to cleanly execute fundamental plays will determine how easily backups can plug in when Week 1 arrives, making depth charts and injury updates critical for early-season fantasy planning.
