The Miami Dolphins offense was looking potent last season when Tua Tagovailoa was in at quarterback. The offense slowed down though when Tua wasn’t in the game as the quarterback dealt with concussions. That has been one of the knocks on Tua so far in his young career, he can’t stay healthy through a full season. Though the quarterback is taking an unusual step to hopefully stay on the field and avoid concussions. Tua has been training in jiu-jitsu, hoping it will teach him how to better protect himself when he takes hits on the football field.
