The Tua fight was awesome. He showed everything thing that fight- Offence, Defence, stamina, power, chin. IMO Ibeabuchi started Tua's decline. Tua never fought with the same workrate or urgency after the Ike fight.

He showed the ability to adapt from boxing Tua to walking Byrd down. None of the current crop have shown these dimensions. In his prime, he would have got to Vlad with his skills and stamina, but his mental health issues and that amount of time way from boxing pretty much rules out a return.

I don't know who'll trouble Vlad at the moment. It will have to be some one that can remain competitive enough over a long fight to tire him out and reach his chin. Maybe Lykyovic can take him deep and wear him out.
