One of the more obvious reasons why Conor McGregor lost to Nate Diaz via second-round rear naked choke back at UFC 196 is the struggle that McGregor encountered to sustain energy. After smashing Diaz's face in for five-straight minutes, the Irishman tired at the worst possible time. Diaz established his range, picked the spent McGregor apart and worked for the finish.
At the rematch at UFC 202 on Aug. 20 from T-Mobile Arena in Las Vegas, Nv., McGregor must display the proper conditioning and pace to get his revenge on Diaz. That key component remains one of the biggest question marks heading into UFC 202.
