Well here's how the Pro Football HOF selection process works. There is an embedded link so you can see a list of all members of the committee which includes a write from each NFL city, & at large members like John Clayton & Len Pasquerelli.

I like the fact that you start with a large pool of players & it goes through 2 rounds of cuts before a final pool of 15 candidates are nominated for election. This would prevent players like Aaron Sele from even appearing on the HOF ballott, let alone receiving a vote!
