AJ plans to outrun Ruiz and to be more technical, instead of facing Ruiz head-on. However, AJ will be in trouble if Ruiz can close the gap and throwing heavy punches. Hopefully not!
I hope AJ will get his title back!
I was shock to see Ruiz weighing more than the first fight, also there's a lot of pictures of him circulating that he has trimmed down for this fight that's why seeing him at almost 300 lbs in the official weigh in, what the hell happened to him? If Ruiz closes the gap and put all the weight around AJ then it will definitely pose a problem, but at that weight he will be a tad slower that their first fight.
The only advantage of Ruiz here is his mass, m x a (acceleration) = Force.
But that is, if he can accelerate in time that Joshua can't react. In the picture it doesn't look like he has attain some mass though, so maybe Ruiz says that he will go in this fight regardless of his weight because he knows that he can beat Joshua here.
In comparison though, Joshua weigh in less in this fight, just a shade about 237 lbs, 10 lbs less that their first fight. So he will be using his speed here in the first couple of rounds, being the lighter of the two and see how it goes for him. He might not go on an early knock out, but he will try to soften Ruiz and use his jab and upper cut.
