Well, yes, thanks to Dak missing most of 2020 due to severe lower leg injury. The stats should benefit the healthy Mahomes, yet they favor Dak. I wonder why?
With the exception of 2020 week 5 game - which Prescott started but didn't finish due to that gruesome injury - the other 49 games are with both QBs being healthy and able to play.
What the 50-game span statistics show is the two quarterbacks have somewhat identical stats over a lengthy time frame- plus their teams have supported them in close to having the same W/L record.
What would have been much better - Brandon Loree would have included several other QBs in that "last 50- start" stretch.
A few longtime league players - Rodgers, Stafford, Cousins, Carr, Goff - along with the younger guys - Jackson, Allen, Burrow, Murray, Tagovailoa.
