Not really, they are not even, yes I know that each one of them won and lost a fight but in the second fight it was obvious who was the best fighter, Joshua lost the first fight because of very specific mistakes in his strategy and his physical condition but in the second fight Ruiz got outboxed and it is obvious that if a third fight happens then the same scenario that we saw in the second will take place and it is not like the public is asking for another fight after how boring the previous one was.
Joshua was out of sorts in the first fight and also not good enough of course. Ruiz was an undisciplined slob in the lead up to second fight. He should've treated that match as the opportunity to emphasise that he wasn't a fluke. Instead he threw it away. Joshua did the total opposite and got back on his trajectory.
I wouldn't be inclined to give him another chance when he had that little respect for the one that truly should have counted. He had the rest of his life to stuff his face and slack off on the training.
Sadly, it is true that Ruize's critique stands as indisputable. I mean everybody picked on how he gained ~ 12kg over the months leading to the fight but I suppose he just enjoyed the luxury lifestyle a little too much and became sloppy by not training as hard as he should have.
If he had taken this more seriously, he would have had a good chance to show the world that his first victory against Anthony wasn't a fluke - he could have re-written history, and I think it would have made boxing matters more interesting, alas Anthony was the 'better man' on the day and put Ruiz in his rightful place!
