It is fun to compare different eras, but what gets you considered for the HOF is how you compare to your contemporary peers.
Aikman really wasn’t all that great compared to his peers, though.
This site does a great job of tracking HOF worthy accomplishments for every position, and ranking all players against their historical peers. Aikman had the 2nd lowest composite score of any QB ever admitted to the HOF. Only Jim Kelly’s was lower, and that was only because of the 0fer in the 4 Super Bowls. Kelly was far more accomplished as a passer, and had a first team All-Pro selection (which Aikman never had). Aikman had a ton of counterparts from his era who were just way better - Favre, Montana, Young, Marino, Elway, Moon, and even Kurt Warner.
The TLDR version - Troy Aikman is probably the worst QB to ever get in to the HOF, and he owes just about all of his inclusion to 3 SB rings when he was a game manager on loaded rosters.
