Is hard for AJ to make the right impression in this fight as this is a difficult match up for him, compared to Wilder vs Brezeale, and this is what many casuals will use to compare. I think he needs to show his boxing skills, that he can fight at close range (which is where Ruiz is dangerous and where Wilder is weakest), box and get the KO mid rounds... if he can. Needs to show levels to his game. He has skils but is def stiff, Ruiz is a tougher fight than Miller imo
