That is because Claudia was a punching bag after the second round, no way Andrade gasses THAT hard. Claudia is usually gassed by the third in 3 rounders whereas Andrade up'd her volume against Hill in Rd 3.
In addition, Claudia's whole game revolves around her wrestling, so once she gassed she had nothing to offer JJ. Even if Andrade slows down, she will definitely bite down on that mouth piece and still throw heat, just not as much volume. I just see it very hard for JJ to earn a 10-8 unless she drops Andrade with a counter shot (unlikely imo) or lands a big elbow (slightly more likely). She doesnt have the edge on the ground either, so even if one of the above scenario's happens, she would still have to have a fairly dominant round standing in addition to that to earn a 10-8.
