Ideally, a great baseball player would be voted into the Hall of Fame regardless of the era his career took place in or when he was eligible on the ballot.
But Hall of Famers aren't always judged completely on their career merits. When a player is eligible and who else is on the ballot in a particular year can play a significant role in determining whether or not he receives the necessary 75 percent of the vote.
Such considerations could become even more important for future Hall of Fame ballots. Beginning with the 2013 class, players and their achievements are going to be judged by playing in the "steroid era," when PED use was prevalent throughout the sport.
Yet how would some players already in the Hall of Fame fare on the current ballot if they were still waiting to be voted in or just became eligible this year? Though it's obviously a hypothetical scenario, here are four players already in Cooperstown who might still be on the outside looking in if they were still on the ballot.
