There are certainly some things whether we get either one of these two young men that you will do to make that transition easier. Starting rookie quarterbacks can be dangerous if you’re not smart about it. What you ask him to do is obviously crucial, But having the right supporting cast is also very important. The Titans don’t have a great supporting cast, But they look set to be relatively strong in the right areas. The biggest part of a quarterback’s supporting cast is his offensive line. His offensive line accounts for the pressure he plays under in the pocket while also playing a major role in establishing the run. Any quarterback with good protection and a strong running game will find it easier to complete passes down the field. In Tennessee, The Titans have the impressive Taylor Lewan at left tackle. Lewan was the team’s first round pick from last year. He wasn’t a full time starter as a rookie but impressed when he replaced Michael Roos during the season. Lewan will protect Mariota’s blind side. He will be aided by left guard Andy Levitre, A very talented player whose career has fallen off somewhat because of injuries. While Levitre and right guard Chance Warmack haven’t lived up to expectations, They could still be an above average guard pairing next season. Levitre’s health will be crucial, While Warmack needs to only continue his development into his third season. Those three pieces should lead the offensive line and help Mariota adjust as a starter, But Mariota should help his offensive line just as much.
