5. Tennessee Titans (9-7)
First game: at Chiefs in wild-card round on Saturday (4:35 p.m. ET on ESPN/ABC/WatchESPN)
Path to Super Bowl LII: The Titans travel to Kansas City to play the Chiefs in the first round. If they win that, they would travel to either New England or Pittsburgh for the divisional round. (New England if the Bills beat the Jaguars, Pittsburgh if the Jags beat the Bills). Win that, and the Titans would find themselves in an AFC Championship Game against either the Patriots, Steelers, Jaguars or Bills. The only way it would be a home game is if the opponent were the Bills.
Reason for hope: Uhhh ... they beat the Jaguars twice, which helps give them confidence they can beat the Jaguars. And hey, if DeMarco Murray can get back healthy, they have a 1-2 running back punch that can theoretically help them control games and maybe win ugly.
Reason for concern: They'd lost three games in a row before Sunday's playoff-clinching victory over the Jags, and they really haven't looked good in awhile. Marcus Mariota had 12 touchdown passes and 15 interceptions heading into Sunday's regular-season finale. The Titans have not been able to get the passing game going at all. Talk about coach Mike Mularkey's job security can't be helping matters.
X factor: Marcus Mariota. The dazzling young quarterback out of Oregon entered this season seemingly poised to make a big leap, and he did not. But the playoffs offer a fresh slate, and Mariota does bring a unique skill set with his ability to run as well as pass. If he gets on a roll, he could make a little magic.
