I'm not sure how it compares to other sports, but I was listening to the Rich Eisen Podcast and he was talking to Joe Horrigan, the vice president of communications and exhibits for the Hall of Fame. They had a fairly interesting discussion that eventually drifted into the theory of some people not nominating certain players because they may have rubbed the media the wrong way or whatever. This has led to some belief to maybe why players like Cris Carter have been left out for years and why guys like Curtis Martin have gotten in so quickly. Joe Horrigan reassured Eisen that at the Pro Football Hall of Fame they are quite strict about advising the people that do vote to not include anything having to do with a player's persona, off the field issues good or bad into their voting decision-making. Apparently they reiterate this countless times.
Well I'm not so sure about the voters going that route (although I'm sure it's happened a few times), but what do you think of the entire process? From how the voters are chosen to the actual decision making procedure? I'm not so clear on it myself, but it is explained on the podcast if you want to listen. I happened to be drawing at the time so I wasn't paying attention 100%.
