Bonds only hit more than 50 HR in a season once.
During the same season that several other hitters all reached career highs in HR.
His ‘01 is what happens when a guy with regular 35-45 HR power has a season with good batted ball luck.
So many don’t understand how big the impact of random variation is in baseball.
They think Brady Anderson’s 50 HR season is a PED thing, when it’s almost 100% random variation: Ballpark and batted ball distribution. You’ll have an outlier like that roughly every 7 years: Brady Anderson, Bonds’ 2001 (what happens when the outlier occurs with an already great player, and it wasn’t even that extreme an outlier), Davey Johnson, Ned Williamson, Tilly Walker, Jacoby Ellsbury, Chase Headley, Jose Bautista, Aaron Hill, Mike Donlin, etc…). Most outliers are from guys (the majority of players) that hit fewer than 25 HR, so them still hitting fewer than 30 isn’t noticeable or significant. Or when a 3-5 HR guy hits 10-12.
Bonds is what happens when greatness overlaps with ball changes and expansion. Look at HR rates every expansion (and he got two in his career). Plus, known ball changes that livened the ball: 1872, 1920, 1930, 1946, ‘86, mid-‘93, ‘99, ‘01, mid-15 (not to mention the ones that deadened it: ‘31, ‘37, 42, ‘88, 2021). Of which Bonds also had his career overlap with four! Four lively ball changes and two expansions (including a ball change overlapping an expansion).
Study after study has shown that impact of PEDs on baseball has little to no impact on performance (at most Bonds gained roughly 50-55 career HR, though most studies have him in the 15-25 range, and these are all almost entirely due to playing more games from injury recovery). It’s only impact is on injury recovery, which lets star players play more games every season. So McGwire played 150+ instead of the 90-130 he’d been getting, Bonds came back from knee injury and played full seasons, Ripken played every day, etc… guys who play more games will put up more counting stats. Their relative rates didn’t differ from their career relative norms in production though.
‘01 is when post-expansion lively ball changes meet batted ball luck. His career is one of steady dominance and the BB are what really set him apart, and those aren’t controversial.
