Lombardi's kind of a special case. He died while he was still coaching in 1970 and then was immediately inducted in 1971 (bypassing the typical 5-year wait for eligibility). I guess that makes him a zeroth-ballot hall of famer?
I just double checked the sources and (this may rock you to the core as it has me) Leaf is not only not a first-ballot inductee, he is not in the hall of fame at all. This outrage must be redressed and I encourage civil disobedience, riots, and outright revolution until it is.
It's very interesting that he was a 1st Ballot, while someone like Phil Simms or Ken Anderson are still not even in the HOF. I think he belongs in (along with Simms and Anderson), but I'm surprised he was a 1st ballot.
I think it had to do with being a part of a trio and the 3 rings they won together, the reason why Irvin didn't make 1st ballot was his off field incidents or he would have as well. They were the dominate team for 5-6 year period. I know San Fran won a year in there but it was still the Cowboys mostly. Kind of like the Raiders and Steelers of the 70s.
Surprised Fran Tarkenton didn't make it on the first ballot. As Wikipedia says, "At the time of his retirement, Tarkenton owned every major quarterback record."

"On February 2, 2013, Strahan failed to be voted into the Pro Football Hall of Fame; 2013 was his first year of eligibility."
