I love talking about all time qbs. Your list is fine but theres guys I dont like. Granted I have a whole criteria for judging qb legacy, I could prob write a 5 page thesis on the subject I love it so much.
manning, montana, brady, favre, young, elway, brees, marino, aikman, unitas is a rough look at a top 10 list all time. I might waver on those but top 4 is set for me. Marino was erased by favre and didnt win a sb so he cant be avove him. Bradshaw wasnt very good, the steel curtain was. Tarkenton didnt win and was all flash. Fouts was just a bearded guy who didnt win and a system qb. I hesitate to put unitas there but he was so good for his time it feels wrong to not include him.
I could make the argument Peyton needs 1 more sb to pass montana but considering age and neck surgery its just too much, hes the best all time.
I would disagree about Marino.
The guy was just flat out a great QB...ring or not.
Id put him better than Favre and IMO, #3 behind Montana and Manning.
