Have Steroids Changed Baseball?

From the conclusion of Art DeVany's new research on Steroids and Home Run Hitting:

"There is a lot of speculation about steroid use in MLB, but the evidence is mostly anecdotal, misleading and incomplete. It is surely not a basis for public policy. Unless more substantial evidence is produced, Congress should just move on to some other 'burning' issue. My opinion is that there will be no evidence linking steroids and home runs; we have seen the evidence already and it does not support the proposition that home run hitting has fundamentally changed. . . ."
