Most people don't know individual greatness other than rings, which are the result of a team.
It is not always fair to compare athletes in different era's especially with rule changes. To say Joe Montana and Steve Young had great players around them diminishes their accomplishments is also not totally fair. Rings as a measure of greatness is also not the only measure of a quarterback.
Being realistic on Elway....he is quite frankly one of the most overrated QB's in history. I am waiting for the Elway fan to tell me about all of his 4th quarter comebacks. I would say a great QB takes the lead in the first quarter and doesn't look back and doesn't have to make comebacks.
In regards to the talent around him. I will use Brady as an example. In general Tom Brady has had below average receivers that he has made better by hitting them between the numbers. His low number of interceptions is also very impressive.... made even more impressive at his age.
Elway career numbers: 56.9% completion percentage 300 TD's and 226 Interceptions 7.1 Y/A and 12.5 Y/C
Brady career numbers: 63.8% completion percentage 456 TD's and 152 Interceptions 7.5 Y/A and 11.7 Y/C
How could anyone in their right mind say Elway is better. Or are the numbers lying?
Another note he only won his superbowls when he wasn't needed (Terrel Davis running the ball and the second one with a strong defense. In the playoffs that year he completed 52% of passes and threw 3 TD's).
Second grade may be the longest 10 years of some peoples lives
