Which made Canseco’s second benefactor — Mike Wallace — all the more important. John Hamlin, a producer at 60 Minutes , had gotten a tip about Canseco’s book from a friend at another network. (The friend couldn’t act on it because his employer was a Major League Baseball rights holder.) Hamlin began calling baseball people and confirming the details. Almost no one would talk on the record, but they suggested that Canseco’s account was true. One of the few allegations Hamlin couldn’t verify was Canseco’s insistence that Roger Clemens was juicing.
It thus becomes quite impossible to believe in any theory that speaks of "boosting" power in modern times, simply because there has been no such boost . Here's a blow-up graph of the so-called "steroid era", starting at 1982 (because 1981 was strike-shortened and thus not a good data point). Understand that in this graph nothing has been "spliced out" save the single ball juicing of 1993/1994 (whether 1993 was or was not post-juicing is still debated); the numbers on the left would change were earlier splicings and wartime smoothings dropped, but the shape and scale of the graph would be unchanged.
