Tua would find a way to win always. Briggs just doesn't have the skills and his power won't bail him out in this fight.
briggs would have early success and keep tua at bay in the early rounds, but tua would eventually close in on him knocking him out, briggs didn't exactly have the best chin.
Let's say both men land full-force simultaneously... Are we really scratching our heads wondering which one stays on his feet?
