Damn hard to predict. Nova has fearsome power but throws himself off balance often enough trying to land that power. I reckon Robeisy can not only outbox him but possibly put him away late if he doesn't get clipped by an unexpected power punch. Nova will be very dangerous as long as he's in there though, you know he won't go out of there easily if he can help it.
Should be an easy W for Ramirez. Think he stops Nova at some point with a barrage of punches. Nova looks like he doesn't like getting hit. Ramirez isn't a classic puncher but he's accurate and has the speed too. Anyways i don't see Nova winning many rounds here.
