NASHVILLE, Tenn. -- This offseason has been about putting quarterback Marcus Mariota in position to succeed.
The Tennessee Titans exercised the fifth-year option on his rookie contract during the 2018 offseason, but Mariota still hasn't proved he can be a franchise cornerstone -- never finishing higher than 13th in Total QBR during his four seasons in the league -- and he's not under contract beyond 2019.
There have been plenty of excuses for Mariota's inability to firmly establish himself after being the No. 2 overall pick in the 2015 NFL draft, with injuries certainly a factor.
