My brother and I were discussing QBs, I've seen a lot or as my brother put it, he has seen all the greats since Otto Graham. In any given year in the NFL there are a few elite QBs. Then a few guys that have no business starting, but are because of injuries or because some team has an investment in them. There are some rookies, who I think deserve a pass. Then there is all the other guys.
The elite guys right now, in my opinion, are Payton Manning, Brady, Brees, Rogers and Roethlisberger. I'm basing this on having won Super Bowls and body of work. None of these guys were drafted in the same year. Of those guys only Manning and Brady can carry a team without much talent, and they have proven that. Payton was drafted in 1998. How many QBs have been drafted by NFL teams since 1998? Yes there have been other elite guys that have retired but other guys, like Rogers, emerg.
QBs from the ranks of "the othe guys", have won a lot of Super Bowls. What is easier to find, the elite guy or find one of "the other guys", and build a great team around him?
