QB rating, considering everyone in their prime as the OP said:
1. Mahomes(DUH)
2. Burrows
3. Rodgers
4. Stroud
5. Herbert
6. Stafford
7. Purdy
8. Josh Allen
9. Lawrence
10. Russel Wilson
11. Goff
12. Lamar Jackson
13. Hurts
14. Carr
15. Tua
Note: IN THEIR PRIME
That means Rodgers and Stroud are both 28 years old. In a list of how they are right now, Rodgers may not even make the list, Wilson wouldn't, and Stroud wouldn't be near as high.
Oh, and big note: I LEFT DAK OUT BECAUSE HE RUINS THE CONVERSATION. HE IS EASILY IN THIS LIST OTHERWISE
