Yeah Schevy is playing second fiddle to Nunes in greatness talks, and she has two losses to her on the record that she'll never get back. Very bitter woman.
Second fight was very close, no question, but the two clearest rounds (1 and 5) were for the champ. At least two of the other rounds were close enough to be open to interpretation.
Shevy lost fair and square and Nunes deserved the victory. Vanquished Val to the weakest division in the UFC, with the exception of WFW. But even WFW, Nunes had to earn that belt by beating a much better opponent than Shevchenko has ever even fought (with the exception of Amanda herself; who beat her twice). And Nunes absolutely smoked the boogeywoman. Legendary shit. Val doesn't like life in the Lioness's shadow.
EDIT: Val the Vanquished has a nice ring to it
