3 things to watch

1. Red zone kings

Tennessee has been lethal in the red zone this season, scoring touchdowns on an NFL-leading 72.5 percent of their trips inside the opponent’s 20-yard line. Marcus Mariota is a terrific running and passing threat. He has thrown 32 touchdown passes and no interceptions in the red zone in his NFL career. The Broncos have a done a good job in red zone defense, allowing touchdowns on just 51 percent of opponent’s drives inside their 20.

2. Justin Forsett

Denver’s signing of the 31-yearold tailback has received more fanfare than usual, because of his previous success in coach Gary Kubiak’s system. Sunday’s game against the Titans will offer the first glance at how much Forsett, who was released by two teams this season, has left in his tank and what if any change it will have in Devontae Booker’s game.

3. Third-down stalemate

How the Broncos fare against the Titans’ offense on third down could go a long way toward determining the winner Sunday. Tennessee ranks fourth in the NFL, converting 47 percent of its third-down chances. The Broncos’ defense also ranks fourth, allowing a 37 percent conversion rate. It’s a matter of which team imposes its style more. Denver’s defense feasts off third-and-long situations, while Tennessee’s offense thrives on third-and-short plays.
