I think as fans we get biased on who should or shouldn't be HOFers. To me, to be considered for the HOF, one of two things have to present. A. You were the very best at your position. B. You redefined your position and how it was played.
I think in the case of mike I. it would be B. He was soo big and physical, it changed the way the game was played, the types of DB's that had to be drafted and he actually changed the rules of the game because of his style of play.
If you can make a case for a player on either A or B, then he should be considered. If he is/was just a great player, then I don't think he will be or should be in the HOF.
