I think Ruiz would out box Tua just depends how his chin holds up because a prime Tua would get there at least a few times. Ruiz may break down with a prime Tua's pace as well and get caught and taken out.
Don't see one knocking the other out so guess I go with Tua by decision by his better work rate. I felt andy won the parker fight fwiw but peak Tua is probably like ibeabuchi Tua and that's a lot of punches
WAR. But Tua. Im sorry people are really underestimating Tua's quickness here, he was faster than you think and he can actually be scaled to Ruiz in terms of handspeed. Ruiz can definitely throw a quicker volume of blitzing combinations once he starts to exchange but Tua is far more powerful and would gladly exchange with Ruiz on the inside. Ruiz would be landing more early on but he would also be the one taking more damage. Tua hit like a damn semi truck. Also Ruiz does not box negative. He's a pressure fighter/counter puncher. I think you know where this is going. Theres only so much punishment Ruiz can take. Tua Late KO or Tua decision. And the likelyhood is its not going to be the latter
Ruiz significantly overrated here. Probably by Joshua fans who bought it when he celebrated like he'd vanquished a dragon after the rematch. Think about it this way, Parker boxed Ruiz Jr to a standstill. Now think about Parker being in the ring with a prime Ike era Tua. Tua had his shortcomings but Ruiz would have to fight tall at range and keep him off for large portions of the fight. He could do it but I favour Tua catching him in an exchange at some point.
That's a way to look at it. Did you know Tua KO'd 2 two-time heavyweight champions inside 50 seconds combined?
Going to have to change my predication after what we saw in Ruiz/Arreola. Tua doesn't need to grind him down at all, Tua goes in there and KTFO of Ruiz early. When you stand with Ruiz he's dangerous but he's also vulnerable. The ease with which Arreoal landed left hooks doesn't bode well vs Tua.
I favored to to KO Ruiz even before the Arreola fight. Now it's almost a forgone conclusion. If Ruiz shows an excellent performance and an iron chin at world level in the future I'll change my opinion but now Tua by destruction, just like he did that other Ruiz
