from 1992 to 2007 Barry Bonds' lowest .OPS (the most important metric to determine how good of a hitter someone is) was .999.
Griffey only had an .OPS over 1.000 4 times and was only over .900 TWICE from 2000-2010.
and here is my best Barry Bonds proof that steroids didn't suddenly turn him from star to superstar...that he was always superstar
1993: 129/46/123 .336/.458/1.136 (29 SBs)
1994: (Strike Season) 37 HR's in 112 games
He was raking better than Miguel freaking Cabrera in 1993. He was on pace for like 55 HR's in 1994.
Barry Bonds was always the best in the game. Steroids just turned him into a guy that somehow managed to get on base 61% of the time in a single year
