Check out the above graphic.
It clearly shows the top 22 long-ball baseball players (including
Rodriguez) and their performance by age.
You can clearly see:
1/ Babe Ruth was on some sort of drug, probably steroids, starting at
2/ Rodriguez is going to break Bonds record, and probably has been on
steroids since birth
3/ Bonds only started using steroids at age 35
4/ Palmeiro deserves credit for being the most consistent player--note
his performance did not diminish at all with age. He might in fact be
the best "age-adjusted, and for his ability, the best" home-run hitter
of all time.
