Obviously, one of her biggest "defects" (according to some analysts who clearly know more about MMA than me) is her choice of a coach who is terrible at his job. If true, that he failed to adequately prepare her to face strikers, than her only MMA related choice would be to change to someone who knows how to properly prepare his/her fighters.
But at age 30 (or so) I wonder if she has the time/willingness to undergo several years of re-training with no assurance she'd be successful?
She's already had overtures from WWE, and she's done some acting.... either (or both) could provide immediate gratification (and money) with little downside - other than the chance of failing at either/both of those careers after several nice paydays!
Ronda (it's assumed) no longer needs money - so (if true) that means MMA is no longer a requirement for her financially. "Entertainment" seems a wiser/safer choice; one where she could resurrect her reputation and become a "star" again.
I'd much rather see her doing something "legit" (even WWE) rather than lower herself to XXX-rated MMA-ish bouts which are merely porn parody and beneath her.
