The only things that make me wonder about her future is her TKO loss to Cat Zingano and her lack of stamina that begins around the end of the second round. Cat was able to absorb her punches and eventually win the fight in the 3rd. Shevchenko, who beat Holm, could take the hits as well but lost to Nunes in a decision.
It seems to me like Nunes is a feast or famine type of fighter. She's a terror for the first 8 minutes, but once the 3rd, 4th, and 5th rounds roll up, she's very human. Kinda like the woman version of Conor McGregor in the octagon.
