Remember the Titans? You'd better do so.
The Tennessee Titans suddenly look like world beaters. Or, at least, a solid choice to win the AFC South.
They have won four straight and six of seven to climb into a tie for the division lead with the Texans. Houston comes off a monumental crash after its superb victory against New England.
Since switching from Marcus Mariota — where will he be quarterbacking next year — to Ryan Tannehill, Tennessee has averaged 31.4 points a game, second most in the NFL in that span. The Titans also have 27 touchdowns over the past seven games after getting 11 through the first six games.
