As Marcus Mariota made his way to Radio Row early this morning, the temperature outside was minus-8. But the Titans quarterback ditched his coat before heading into Mall of America. A vocal workout was set to begin, as well as a physical one, as he prepared to make the rounds here at Super Bowl LII. Mariota talked with Titans Online at 5:40 a.m. about what everyone wanted to know, from the coaching change to his new offensive coordinator to what’s ahead in 2018. “I have had a few conversations, and I got to meet him when I was in Nashville,” Mariota said of new head coach Mike Vrabel, hired last month to replace Mike Mularkey. “I’m just very excited. His vision, the direction he wants to take the team, it is one that I am very excited to be a part of. It is going to be a lot of fun. I think he is a very competitive guy. He just loves to win games and put us in the best position possible and I look forward to getting to work and I can’t wait to get started.” Mariota said he’s also looking forward to working with new offensive coordinator Matt LaFleur, who joined the Titans after spending one year as the offensive coordinator for the Los Angeles Rams, who ranked first in the NFL in scoring and 10th in total offense in 2017. In his first season with the Rams, LaFleur was instrumental in the development of quarterback Jared Goff, who threw for 3,804 yards with 28 touchdowns in 2017 en route to reaching the Pro Bowl. LaFleur has also worked with Falcons quarterback Matt Ryan, and helped Robert Griffin III during his days with the Redskins. He’s expected to help Mariota take a bigger leap in 2018.
