Conspiracy Strikes - Pittsburgh Drug Trials

In the 1980s MLB had it's third biggest scandal of that decade with a cocaine debacle that surrounded the Pittsburgh Pirates and a few other players in MLB. Including Tim Raines and Keith Hernandez. I also go into the drug testing that MLB wanted and it was blocked by the Player's Union. Just right before the Steroid era took part.

Would Jose Fernandez and Tyler Skaggs be alive if these drug tests were enforced starting in the 80s?
