Fouts and Marino are in as is Warren Moon, Jim Kelly and Tarkenton all who never won a the Championship. Marino is arguable one of the 5 greatest QB's in NFL history. I didn't think Moon should have gone in and Fouts I can see but I don't view him as an all time great in Marino's class. I always thought Stabler should have gone in ahead of both Moon and Fouts both of whom I would put in ahead of Palmer even with a SB ring.
Looking at Palmer era, to me he ranks way behind Brady, River's, both Manning, Rothlisberger, Rodgers, Luck, Ryan and Brees. You put Palmer in with a SB and you have to start considering Joe Flacco.
