I'm not sure saying "If Ronda hadn't lost..." is really a fair way to view it though. She did lose. Badly. And she got smashed and the blueprint is there on how to beat her. Obviously you need the skills to do it, but Nunes striking (for a couple rounds anyway) is plenty good enough to bloody Ronda up like Holly did. The reality is that Ronda lost that fight the first few punches that rocked her.
Nunes doesn't need a TD, she needs to land some sig strikes early. Then we see how RR reacts. Will she go spastic again? Or having been through it will she keep her composure this time. That's the biggest question for me. The chance is of course always there that she gains the clinch before she gets hit, throws Nunes on her head, and subs her. But if that doesn't happen, how will Ronda react to getting her head snapped back again? That has to be the biggest question in this fight.
