I'm confused here. Why would we mortgage the future on Mariota? Mariota is like Gardner Minshew. He would be a low-cost option in case Goff doesn't step his game up. Watson is the guy on which you mortgage the future.
Mariotta looked good off the bench, but it didn't take long for him to revert to form.
In short spurts, Mariotta can be a really good #2, but he's just not a #1.
