QB's sucked.
It's no wonder that Beau's feet bailed him out in a terrible scheme similar to how Taysom's running ability helped to hide many of the inadequacies of the offensive scheme in 2016 as well.
It's no secret that Ty's offense was terrible, particularly the passing aspect.
Tanner is a better passer than Beau, and he has proven it not only last year, but the previous years before that as well.
I'd rather have Tanner at QB than Beau, especially if the offense is able to pass the ball this year, unlike last year.
