Mariota's work in refining his technique started back in February, when he traveled to California not long after the 2017 season.

His mission heading into the offseason focused on improving his base, and his footwork. In 2017, Mariota threw for 3,232 yards with 13 touchdowns and 15 interceptions while guiding the Titans into the playoffs.

After reviewing his season, however, Mariota knew he needed to make some adjustments. Mariota began working on widening his base, something he believes will improve his accuracy. Mariota first brought up the issue to reporters in April, and when asked for an update last week, he said he's making progress.

With a solid base, Mariota believes he'll be able to get rid of the ball faster, while making accurate throws.

"It's coming," he said. "It's tough because it's hard to break old habits. I think for a long time I've been playing with such a narrow base. If I'm able to accomplish, really, that goal of mine, to stay in a good solid base throughout, I think I can make a lot of the throws that are asked of me in this offense. As I continue to be out here, I've just got to continue to be mindful of it and find ways to just self-correct and just get better.

"It really started back in February, just working out. It's something that I had worked on in California and was really kind of focusing on that. It's gotten better, I think being out here. I'm fortunate that Matt (LaFleur) and Pat (O'Hara) and the rest of the offensive staff, they continue to incorporate those principles of having a base, and being able to throw from that platform. Again, as I go forward I think if I can continue to find that base, I can do my best to make all the throws."
