Why is this significant by any chance?

Tim Boyle had a higher passer rating than Zach in 8 out of Zach’s 10 games (Zach was slightly higher in the bills comeback win, and in the chiefs game)

He also had a higher completion percentage than Zach in 9/10 games (Zach had a completion percentage of 73.1% in the win vs the Broncos)

Just something to think about.
