They remain the true home run kings...if the game is to have any value, any credibility whatsoever, Selig has to unilaterally restore Roger Maris and Hank Aaron to their positions as the all-time home run kings. Maris' record of 61 home runs in a season has not been surpassed, and Aaron's record of 755 home runs has not been shattered. Not really. Not in any sort of athletically credible way.
As for A-Rod, maybe he'll do the honorable thing and go into film and TV...something medical perhaps...Grey's Anatomy? Private Practice?
