Remember, this is a quick study on the most recent 48 games (or 3 season equivalent)....
Also you cant add rushing TDs without subtracting fumbles lost.
Here are the completion percentages over the last 48 games
- Prescott 65.9%
- Goff 64.7%
- Wentz 62.9%
I'm pretty sure this is captured to some degree in QB rating, but there you go.
As for Rushing TDs - fumbles....over the last 48 games....I'd have to dig in.
It is true that you can do a TD-turnover differential by adding in the rushing TDs and subtracting the total fumbles.
Update.
I looked up Dak's rushing TDs and lost fumbles over the last 48 games.
he had 16 rushing TDs and 14 lost fumbles.....so improved his differential by 2.
