If anything, their fights with Andrade and Joanna should give you an idea of how much of a mismatch this is. Valentina outwrestled Andrade so easy while jessica was slamming Rose and was always the one getting takedowns there. Joanna was very competitive against Rose when she didn't get KO and almost won that rematch but was completely outclassed by Val.
There are levels to this. This was ridiculous when it was suggested about Zhang and is still ridiculous now with Rose.
What's crazy is that these top contenders at 115 (Zhang, Rose, Joanna, Andrade, Suarez) could easily beat the top contenders at 125 (Chookigian, Eye, Maia, Calderwood, Calvillo, Murphy, etc...). Which gives you an idea of how many levels Val is among the other 125ers. Based on division dominance, she is P4P #1
