Why is it a NC with an illegal knee, but when Jones' downward elbow it's a loss? 
Weird.
Isnt it a NC when a cut occurs that must end the fight? Was it the cut on Pearson? He was otherwise fit to continue.
Maybe it was due to the cut. I think Buffer said stoppage due to an illegal strike. Honestly, I'm not sure.
I think it was the cut, which was also questionable as it wasnt near the eyes but "I'm not a doctor."
its like when royce roided vs saku
its still listed as a win
wtf?
I believe it's a no contest b/c the referee deemed the knee an accidental illegal strike whereas ref in Jones fight called it an intentional illegal strike? 
Chris - I believe it's a no contest b/c the referee deemed the knee an accidental illegal strike whereas ref in Jones fight called it an intentional illegal strike?Yeah that's right.
The ref. has the discretion to determine whether a fight ending foul is intentional or unintentional.
So an intentional fight ending foul like Jones/Hamil was a DQ win for Hamil.
Then you have Pearson/Guillard which was ended by an unintentional foul, so it is considered a no contest.
Jones threw the illegal blows intentionally. Melvin did not

Thank you, Chris. That makes sense.
