A fairly good read on Tua and the offense:
Heisman Film Room: Tua Tagovailoa is a star in the making
We're used to Alabama's running backs winning or competing for the Heisman. It often appears the voters hand the thing out as a kind of team award - "You guys were dominant, so here's a trophy for the figurehead on offense."
This year will be different. Finally, Nick Saban has a quarterback with genuine Heisman aspirations (feel free to groan).
Tua Tagovailoa enters as a heavy favorite to make it to New York after his performance in the national title game made him a household name.
The only thing holding him back: a quarterback competition. The new redshirt rule and Jalen Hurts' 24-2 career record give the veteran quarterback an outside shot of reclaiming his spot from the young pup.
Alabama shouldn't give it to him.
Tagovailoa stepped in against a snarling, fire-breathing Georgia defense on the grandest college stage of all and more than held his own. Freshmen don't marshal come-from-behind victories while coming off the bench against a top-10 defense with NFL-caliber speed. What he did was bonkers, really.
His performance wasn't perfect, but it was pretty damn impressive for a guy just trying to find his bearings.
