The Titans improved to 2-0 in the preseason with Saturday's 16-15 victory over the Seattle Seahawks, and they did so with the help of an unlikely hero. Rookie kicker Brayden Narveson made three-fourth-quarter field goals, including a 59-yarder that gave Tennessee its first lead and a 46-yard game-winner as time expired. Even so, the best he can hope is that it was enough for another team to want to sign him. ... Malik Willis was the Titans' starting quarterback against the Seahawks, but in the critical moments of that contest it was Mason Rudolph under center. That probably says all there is to say about whether Willis has any chance to be Will Levis' backup. ... While the issue at backup quarterback might be settled, other spots are up for grabs. Perhaps the most interesting battle is between Hassan Haskins and Julius Chestnut for the final running back spot. Others like linebacker Chance Campbell, wide receiver Jha'Quan Jackson, outside linebacker Jaylen Harrell and tight end David Martin-Robinson are among those who have found ways to stand out and have made strong cases to make the final roster. ... This week, Netflix premiered its latest episode of Untold, this one on former Titans quarterback Steve McNair and the circumstances surrounding his murder. The program did not reveal any new information except for one notable item -- a long-sought revelation from former coach Jeff Fisher. McNair's college glory days at Alcorn State also were detailed this week in an ESPN.com story. ... The starters will be back in action Sunday against the New Orleans Saints, and there are reasons to think it will be a beneficial performance in the final prep for the regular season.
