Not only that, but how can you ever show that Roids was the sole reason for their success? What about the new/smaller stadiums, expansion, juiced balls etc.
Marris hit 61 in a 162 game season (longer than Ruth had) and he did it in an expansion year. So why restore his record? He had outside help as well.
My point, like Gant's, is that it's impossible to prove any of these factors lead to X amount of additional homeruns. The records should stand. The records will stand. People of our generation will always look down on their records (much like many looked down on Marris's), but in 50 years it will be just another blip on the baseball record book...
