I hope you're mocking those sportswriters and not being serious, because I have heard that said before, and every time it sounds even stupider. Babe Ruth didn't get in unanimously because even decades ago, people sucked. Someone didn't vote for him because he said something mean to them once. Somebody didn't vote for Hank Aaron or Willie Mays probably because they still hate black people (It was a while ago, and with 400 people voting, there had to be at least one racist in there, right?). Someone didn't vote for Ted Williams because he had an occasional reputation as 'unfriendly to the media/fans'. Someone didn't vote for Ty Cobb because Ty Cobb was one of the most unlikable human beings in the history of human civilization. Any reason that people come up with that doesn't include something related to the player's on-field achievements is just stupid. The past is the past. Just because someone didn't get in unanimously fifty or sixty or seventy years ago, does not mean that people shouldn't get in unanimously now. Ken Griffey Jr. put up amazing numbers for years, and let himself fall apart like a snowman in early spring during the midst of the steroid era. There was never a hint of PED suspicion surrounding him. He could have taken them and maybe, just maybe extended his career and stats a little bit, staved off some of the physical deterioration. But he didn't, at least, it seems that way, and without evidence or even innuendo, that should be good enough. But even without the nobility of pure play during a dirty time, he was still, by the numbers and by the heart, one of the greatest outfielders to ever play the game.
The three guys who didn't vote for him, whether it was for personal reasons or because of some ridiculous arcane superstition about unanimity, should have their voting privileges revoked and then be fed to crocodiles.
