A problem with the list such as the one above is that you're comparing players from different eras and rules, e.g., Marino vs. Brady. In addition, it gives insufficient weight to players from the 40s through 60s. Where is Otto Graham or Sammy Baugh. From what I know of these greats of the game good players of today wouldn't be mentioned in the same breath. This is no insult to Eli Manning or other good QBs but they're just not in the same league.
A notable omission from the above list is Roethlisberger. He brings to mind some great QBs of yesteryear. Another one is Steve Young.
These lists are all very subjective.
You are absolutely correct, Brad, my list does not include any players who I personally have not seen playing either in person, on TV or on film. For me it is impossible to appropriately consider the skills of these amazing players, as (1) I have no experience of their skills and (2) frankly, it was a totally different, tougher, more physical game, played entirely outside, with very different rules. Perhaps I should have qualified my list as "the top 10 quarterbacks of the modern (TV Coverage) era."
Steve Young would be #11 on my list. He only won one title as a starter, and was outdueled by Aikman consistently throughout his career, only getting past the Cowboys to the superbowl once. He had the benefit of throwing to Jerry Rice, the greatest receiver, and arguably greatest player of all time. That being said, he had great numbers, was incredibly mobile, and his performance against the outmatched Chargers in his one superbowl was exceptional.
Ben Roethlisberger is, like Eli, on the outside looking in right now. He is 2-1 in 3 superbowls, and his numbers in 2 out of his 3 superbowls, are, frankly subpar. He is tough, but very injury prone. His greatest asset is his size, he extends plays by shrugging off hits, enabling his receivers to break open late. As of this minute, I have him in front of Eli, but if Eli wins his next two games he will move one slot ahead of Big Ben on my list, taking over first place on the QB class of 2004.
That being said, what a draft that was: San Diego took Eli #1, traded him to the Giants for the #4 pick, Philip Rivers, and the Steelers took Big Ben #8. Ben has two titles, Eli might get his 2nd ring this season, and, other than this season, Rivers statistically has out played them both. I would not at all be surprised if the 2004 QB Class had 5 or more Superbowl Rings before it is done.
