Lol kind of is!
But there are those few select fighters whose prime ended almost immediately as soon as USADA partnered and announced the comprehensive year round drug testing. Johny is the poster boy for that, 16-3 until the day they announced the testing program, and 17-3 before it had any bearing on him as he fought less than a month after the announcement of the program (being eligible to be tested year round etc). He called for GSP to undergo additional testing for their fight, which GSP complied and exceeded with, but refused to take it himself.
He followed that up by disappearing for a year and then losing 5 of 6 fights, only winning against another roid monkey in Hector Lombar, who lost 6 straight after shockingly being popped for anabolic steroids.
Fails the old sniff test.
