Mike White competed with Trubisky for the QB2 spot but ultimately did not win Buffalo’s backup role, highlighting the depth-chart uncertainty at QB2 across the league.

White looms as the likely QB3 on the practice squad; Buechele’s performance didn’t fully answer the QB hierarchy, leaving White in a secure but watchful position behind the top two.

White split equal playing time with Trubisky, offering a glimpse at Bills’ QB depth. His second-half exposure hints at potential if Allen misses time, but the sample is too small to draw firm conclusions about Week 1 certainty.

Mike White served as the Bills’ contemporaneous quarterback in this preseason game, providing depth behind the starter. His presence on the field against Chicago highlights Buffalo’s QB depth and potential opportunities for White if injuries press the Bills’ Week 1 plan.

White’s showcase for Buffalo’s backup reps was uneven, with the context of a game against Bears reserves. His performance could influence whether he remains in the QB2 conversation or cedes ground to Trubisky as the lineup solidifies ahead of Week 1.
