The Titans are a team that is built around the ability of their offensive line to allow their power back Derrick Henry to just run through people. As a result, this has allowed Ryan Tannehill the opportunity to play well off the back of play-action, as part of an incredibly efficient passing game.
During the offseason, the team managed to add Julio Jones to its ranks- who will fill the role as a (likely) secondary receiver on the team. That could lead to a more balanced offense, but it’s more likely that the team continues to operate in a similar way. With efficient passes off play-action.
