Here is a link to a .pdf version of the actual
Tobin (2008) study. Interesting.
He addresses the issue of the mounds, ballpark dimensions, and admission of black players here, as well (essentially demonstrating that there has never been the enormous spike in HR numbers with any of these changes, whereas the HR totals dramatically increased in the mid-90s well beyond any other period in baseball history...like that's new news).
Dont find the article particularly convincing. It ignores league wide analysis and makes several glaring assumptions. Most outlandish to me is the assertion of 10% more muscle mass not effecting the length and technique of a batters swing. He's obviously doing some basic Newtonian calculations without any understanding of the bio-mechanics. He just keeps on simplifying mechanics and guessing at variables. It feels like the framework to start an actual analysis with large sections intended to be revisited with actual data.
You're probably right and there's nothing to it. The huge spike in HRs league-wide, highlighted by the Brady Andersons, Brett Boones, Ken Caminitis, Bonds, Sosas, McGwires, et al...it's probably now that I think about it the result of global warming and not steroids.I'd be interested to see your data that demonstrates the length and technique of batters' swings are
adversely affected by 10% increases in muscle mass. You seem to value empirical studies and not conjecture. Do you have any data to support this?
Brady Anderson An interesting take on Brady Anderson, imo, and part of the reason people generally need to temper their assertions re: steroids.And the spike in HRs examined by the study you linked is only the top few hitters in the league, he's not examining the league wide trends which have alot more data points and should be less susceptible to random fluctuations and singular outliers.
Im not the one making claims of 30-70% HR inflation. Im not the one trying to prove anything. Don't see why I need data. But considering the intricate movements in a swing, its hard to imagine having your muscles increase in size by 10% all around, without and growth in the bone structure, and being able to have an identical swing. The swing will change, it might magnify or minimize the effects of the increased muscle mass. I dont know. Then again Im not drawing conclusions based upon the assumption that the effect would be zero.
And the spike in HRs examined by the study you linked is only the top few hitters in the league, he's not examining the league wide trends which have alot more data points and should be less susceptible to random fluctuations and singular outliers. You aren't denying that HR numbers have spiked as a league-wide trend are you? Seems like an interesting point to make, if you concede it, already.Nevertheless, all I'm pointing out is that you are using words like, "considering..." and "it's hard to imagine..." and then making a statement/assertion (i.e., "the swing will change") without reference to actual data to support these claims. Note: I do not doubt that there is an association, but I am also open to using a logical argument when the evidence does not
yet prove the theory. Borrowing from the old adage: the absence of evidence is not evidence for its absence.
Yet, the basis of you being a steroids skeptic/denier seems to be that no one has risen to the challenge to provide incontrovertible proof that steroids contributes to significant (and robust) improvement in a particular batting category or phenotype (e.g., home runs/power).
Nevertheless, I believe (as you are free to deny/remain skeptical) that the totality of circumstantial evidence is damning, that steady reasoning supports the association between steroids

ower. In the absence of any plausible alternative that can be characterized by data in some peer-reviewed literature or elsewhere
