It that was a fluke....then I don't know what a non-fluke is. Ronda got her butt kicked 6 ways to Sunday in that fight. The outcome might be different now, but on that night, with what both fighters brought into the cage, Holm was going to take that fight 8 or 9 times out of 10, with at least 3 or 4 of those wins being by KO/TKO. Ronda finally met a chick that had Real-World striking, size, strength, TDD, and most importantly fight I.Q.. That last bit was the most crucial of it all. Holly is not a dumbass, part-time fighter like most of Ronda's victims.
Nunes is going to be a tough fight because she has a lot of those same qualities except that her gas tank sucks just a little bit less than Rousey's. But she's got a killer's instinct...something you don't see from the 135lb division.
