Tito destroyed Mayorga with his power. What were you watching. Mayorga saw the punches coming, that's why he didn't get knocked down by them but got KD by Hoya's hook. Tito seriously damaged Mayorga in that fight.
Roy has no legs anymore. He backs into the ropes and stays there. Watch the Hanshaw fight closely. Roy's timing is COMPLETELY absent, he misses by a foot most of the time and gets maneuvered to the ropes EASILY. Only reason he doesn't get tagged more is cuz Hanshaw has zero accuracy. If Tito is well conditioned and trained seriously for this fight, if he is patient and doesn't try to get Roy out of there too early and systematically finds his range, he stands a very good change of KOing Roy. Roy is a reflex fighter AND is 39... very very bad mix. Tito doesn't rely on reflexes and natural abilities so much. He's a natural puncher and father time + inactivity won't take such a toll on that kind of fighter.
