No *'s

With McGwire's unsurprising admission - my solution to this continuing problem is that every professional & elite sportsman/sportswomen should immediately collaboratively admit to using some form of illicit performance enhancing substance whether they actually have or haven't.

The effect of this is that it will collectively overwhelm all the official sanctioning bodies and WADA into giving everybody a get out of jail free card - amnesty if you will and a do-over. Because if they didn't, it will effectively shut down the sporting business model as we know it. Which is the way professional & elite sports is slowly fading anyway.

The caveat being that future testing isn't a chip in bargained contracts, and each governing body still determines what is illegal, with thorough testing at regular & random intervals. If caught (both A & B samples test positive); zero tolerance, you're banned for life, out on your ass, get another job.

As for the likes of Big Mac and similar with post professional admissions or proof of past abuse - erase all records, impose fines, and remove them from any responsibility and/or connections they may still enjoy with the sport. And like other criminals they may not profit from their past behavior (book deals, appearance fees, movie rights, etc.).
