Not really a Diaz fan & I was expecting this to happen, still sad tho, mostly because Bendo is one of the most annoying ppl in the UFC.
Benson is a horrible matchup for Nate, kicks and wrestling, didn't look good for Diaz. It could have been overcome, The Diaz brothers can win bad matchups due to toughness & cardio, problem here was Benson has excellent cardio as well.
If the fight between Nick and GSP ever happens this is exactly what I think will happen. GSP would use his athleticism, strength, speed & wrestling to bully Nick, and when at distance just kick the crap out of him.
