Nick Diaz is undoubtedly one of the most popular fighters in mixed martial arts for both reasons good and bad. He is a rebel, controversial, tough as nails and exciting in the cage.
But, with controversy comes baggage. Diaz is currently suspended due to a failed drug test following UFC 143 against Carlos Condit. This was the second time Diaz would be caught red-handed with marijuana in his system.
Diaz is still one of the faces of MMA, so this is troubling. He desperately needs to make a turnaround or he will be left in the dust of a constantly growing sport.
