Antonina has a decent sub game off her back same as her sister, also thats assuming she does get on top which is doubtful. Wouldn't surprise me at all if Antonina hits more takedowns on Roxy than she gets takendown.
Shevchenko's only relevant sub really was on Pena, although she does more actively pursue submissions especially on hurt opponents. I remember watching her really early fights where she'd come out and unload strikes on opponents then snatch a sub. Antonina seems much happier to just continuously beat opponents although the sample size for this is limited.
How is there a discrepancy though? Antonina's been just as successful outside of MMA and not shown any glaring weaknesses in MMA or deficiencies she's just not proven herself as clearly.
Far inferior? I'll admit she's a little less slick and slower but she's still very good and has her own advantages, her use of the Thai plum is excellent for example. Comparing them to the Lima's where one guy is barely UFC level and the other world class is way off.
She looks taller than Valentina but not as heavily muscled to my eye. Maybe she could go up, but not sure how'd she look against bigger bantamweights.
