PHOENIX – Rodger Saffold and a new, to be determined right guard, will help. As will Adam Humphries, a reliable, underneath target.
But beyond other guys on offense, in a giant year for Marcus Mariota, he needs to find ways to stay healthier to be productive for the Titans and to put himself in position to earn a new contract. 
After chronicling Mariota's 2018 injuries, I asked Mike Vrabel and a few other coaches at the NFL Annual Meeting if there is a skill to staying healthy as an NFL quarterback.
