Nunes can't recover after UFC 213 but mostly 2nd fight vs Shevchenko destroyed her career, mainly not because it was close, but because it was extremly boring fight that displeased most of fans. I like Nunes, but her takin on Cyborg is just result of UFC 215.
Both fighters got easy fights after UFC 215... and partially regained some hype, but right now both will have risky fights. Nunes will face Cyborg, and Shevchenko will face Joanna, Nunes will have mountain to climb and Val is going for completely unpredictable oponnent - Joanna's body language is weird after announcing this fights, strangely confident. I'm even confused as her fan.
