If the Bills decide to rest Allen down the stretch of the regular season, they would turn to veteran backup Mitchell Trubisky to lead the team in his absence.

Mitchell Trubisky was elevated from the practice squad ahead of the game against the 49ers, but with both Josh Allen and himself healthy, he was not expected to be active for the matchup.

Mitchell Trubisky's 13 college starts are tied for the fewest by a first-round pick quarterback since 2000, highlighting the raw nature of his development as a player. This context is relevant when considering Anthony Richardson, who has also had limited starting experience, suggesting that both quarterbacks may require more time to refine their skills at the professional level.

Mitchell Trubisky was one of the quarterbacks who started for the Steelers during Johnson's tenure in Pittsburgh. His presence, along with that of Kenny Pickett and Mason Rudolph, contributed to the quarterback uncertainty that Johnson faced while trying to establish himself as a reliable target. This experience with multiple quarterbacks may have helped Johnson enhance his adaptability and route-running skills, making him an attractive trade option for the Ravens.

Mitchell Trubisky stepped in as quarterback for the Bills when Josh Allen was briefly sidelined after a head injury. During his time on the field, Trubisky could not lead the team to a successful drive, resulting in a quick three-and-out before Allen returned.
