We only have one year's worth of stats to draw from on Marcus Mariota, but he was incredibly efficient in the red zone last year, with a 35.6% touchdown rate that is the best among the 56 passers to record at least 30 attempts in the red zone over the past three seasons.

He also has some added red zone appeal because of his rushing ability. He didn't run the ball often last year, with only 32 carries, but he looked great when he did it, recording 252 yards (7.4 yards per attempt) with 2 touchdowns. Among the 15 quarterbacks to run the ball at least 30 times in 2015, he ranked third in Rushing Tennessee Titans coach Mike Mularkey may want to play "exotic smashmouth" football, but over 12 games with Mularkey as head coach last year, the Titans ranked 11th in the league with a 1.52 pass-run ratio in the red zone, leaving plenty of room for optimism about the volume Mariota will see.

Mariota will have some pretty good weapons to use in the red zone as well, and among 111 players with 20-plus red zone targets over the last three seasons, Kendall Wright ranks a surprising 13th with a 36.0% touchdown rate, while Delanie Walker has a solid 26.7%.
