Actually from what I've read the testing procedures this time around is going to be different than the last.
Supposedly Vince has put the testing program into the responsibility of a third party who will be going straight to the public with any positives, as opposed to the previous program where the results went to Vince first who then decided to either suspend, fire or overlook about the offending grappler's positive.
It of course remains to be seen what will happen, I really doubt that a top-flight main-eventer would be suspended if a positive result came in a few weeks before a major PPV.
I thought it was ironic that they will also be testing for cardiac conditioning too, as this is one of the ways Vince used to beat up ole' Verne Gagne back in the day.
Whenever Verne would put on a show with Jerry Blackwell in the headliners, Vince would wait until the day of the show and call the State Athletic Commission, who would of course do a simple high-blood pressure test on Blackwell (which he could never pass), deem him unfit to work and thereby screw up the whole show.
