I'm truly concerned for Ronda in this fight, i'm basing my opinion off of the technical merits of both combatants. Amanda is a far superior technical and power striker than Ronda, the last fighter Ronda faced who had better striking was Holly and... Yeah.
Ronda has far better takedowns and throws, however Amanda is far superior in her Jiu Jitsu. To my knowledge, Ronda has yet to face a legitimate black belt who also has dangerous striking..... Has she faced any black belts? Amanda has competed against legit competition in the BJJ community, and trains with some awesome grapplers in Coconut Creek..... If Ronda gets the fight to the ground, Amanda won't be lost like the other people Ronda has faced.
The X factor/wildcard.... Mentally Amanda is tough, she's ready to go to war and has a nasty streak..... Ronda use to have that, but by all reports, that Ronda is far gone. Her aura of invincibility has been shattered and while she may get that back, she's across the cage from her one of the two most destructive woman in fighting (Cyborg being the first, and I put Nunes a step ahead of JJ just on her brutality).
This isn't the fight Ronda should have taken returning after a year off, riddled with numerous reports of her fragile mental state...... Unfortunately for a fighter of her magnitude, this was one of the only fights for her to take (outside of a rematch with Holly or the Cyborg fight).
