There's not a position with more eyes on it in New Orleans than quarterback. The position already holds elevated importance in general, and now the New Orleans Saints are embarking on a battle between Tyler Shough and Spencer Rattler for the starting role. The worst thing that can happen is they must award that title to someone who didn't earn it.
The last time the Saints had a quarterback battle was just a few years ago between Jameis Winston and Taysom Hill. Winston had a strong offseason and won the job. There was still a role for Hill, but more importantly Winston went and took the job.
