I think both have the power to hurt eachother. Can AJ work out a gameplan to beat Ruiz. He should use his advantages and make them count. He made it too easy for Ruiz last time to fight a fight that suits him.
AJ looks leaner to me, he looks in better shape for the fight. Sparring would have been really important for this fight.
Ruiz will probably come in a bit lighter too but he will still carry excess. AJ handled Parker very comfortably, if he fights a mix between that style and power it should be better for him. If he gets drawn in fully then it’s whoever lands the bigger blows quicker.
