I look at it the same way as the Gomi fight. Conor cracked under the relentless pressure,and the Diaz brothers are very good on capitalizing on those kinds of situations. They dont shoot for double,but if someone wants to jump into their guard in a panic,thats the perfect situation for them to get their stuff off. Conor shot because he couldnt handle the pressure any longer,but i dont think its some calculated effort that Nate submitted him,the oppurtunity presented itself,and thats his natural inclination.
