Is floyd changing the course of

OLYMPIC STYLE testing IS GOOD except some business people in boxing will think otherwise.

Olympic style testing is effective because they track results for months and even years at a time. Many illegal drugs are caught because of very small changes in chemical and hormone balances over a period of time. While I would not be against boxing moving in that direction, considering the many different athletic commissions, it's unlikely that they can effectively test as well as the Olypmics do. I doubt any single Olympic-style test for a fight would be more effective than regular testing.

random drug tests in boxing are about 20 years over due

If it becomes mandatory to take random blood tests. Then we have to give Floyd credit for that.
