The following rookies have at least one QB start under their belt already:
Bryce Young (CAR)
CJ Stroud (HOU)
Anthony Richardson (IND)
Will Levis (TEN)
Aidan O'Connel (LV)
Clayton Tune (ARI)
Dorian Thompson-Robinson (CLE)
Jaren Hall (MIN)
Tyson Bagent (CHI)
and soon to be Tommy DeVito (NYG)
For reference, 2020 had six different rookie QBs start a game (I originally had five before remembering the Kendall Hinton emergency), while 2021 had six and 2022 had seven
