Polian saying he has no clue who he voted for is either an outrageous lie, or he's just proving he's seriously incompetent at this stage to hold a vote and be a voice in this. No in between.
The MVP votes for NFL have to be publicly released, why is it not for the HOF?? Clearly in this timeline and climate too, politics and bias are becoming even bigger factors in these decisions nowadays across all sports. And whatever connections these people have to the players/coaches in some form (market interests for example).
