The NFL Hall of Fame voting is a bit weird in that they are supposed to vote in at least 4 players per year, but no more than 8. This has actually led to somewhat of a backlog in players getting voted in. It also is supposedly a highly political process with cliques within the voters deciding that for whatever reason Player X must be made to wait, vote trading (you vote for my guy, I'll vote for yours), egos of the press members of the voting committee getting in the way, even supposedly many of the press voters refusing to vote for former players/coaches just on the basis of not liking the person for some perceived or real former slight.
