The Tennessee Titans' quarterback situation is quickly transforming from one of the NFL's least productive to one of the NFL's most enviable.
The rookie maintained poise in the face of Rams defensive coordinator Gregg Williams' assortment of blitzes. Mariota fled the tackle box to avoid a potential sack or intentional grounding penalty, displaying the ability to make the right decision under pressure.
Through two preseason games, Mariota has completed 12 of 16 passes (75 percent) for 152 yards.
His backup, Zach Mettenberger, has posted even stronger numbers, riddling second- and third-team defenses for a 122.9 passer rating the past two weeks.
The young quarterback duo has the Titans envisioning future success behind a precocious starter and his high-octane backup.
