Physiological effects of steroids can be estimated reasonably well because it can reasonably be supposed that few if any potential users are going to have significant pre-existing medical problems. But when trying to evaluate mental effects, that supposition has no basis. As Darkes (see farther below) and many others have pointed out, one of the chief failings of many studies of steroids and psychiatry is the failure to design the studies so that the cause-and-effect relationship is not tangled. While there are, in some reports, evidences of some possible correlation of steroid use and mental problems, what few if any of those studies address is which is cause and which effect .
But as much as the game will try to become safer, the players will still be asked to play 162 games a year, not 154, not 140. That's because MLB always protects its statistics, but mostly it's because owners won't be willing to forfeit roughly $2 million to $3 million per home date. There will be no American League and National League, it will all be under one MLB. There will be no Oakland Athletics or Tampa Bay Rays . The game will not expand to Mexico or Japan or Las Vegas. Instead, it will contract from 30 to 28 teams. That will make scheduling easier and more equitable: All teams will play each other six times, 27 times six equals 162. The top 10 teams in the game will make the playoffs.
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.
