A terrified Joshua from the Ruiz rematch gets the decision, if he comes to take Tua out, he may well get taken out himself.
Same as I think. Joshua could box the ears off of Tua but if he decided to be a hero he could end up knocked out.
This, Joshua can win if he runs, he probably doesn't run though in the first fight and as such he gets bombed out
I think a properly motivated Tua (like we saw vs Maskaev) has at least a 30% chance to knock Joshua out even if Joshua is cautious. It will only take one proper left hook connecting for Tua to win this. That being said, i think there is a 70% chance that the cautious Joshua from Ruiz 2 will be able to win a decision.
