The Dolphins are expected to implement for read-option into their offense this season. With OC Bill Lazor, a Chip Kelly disciple, now running the show in Miami, he's expected to take advantage of Ryan Tannehill's athleticism. Tannehill, as a former college receiver, has piled up just 449 yards rushing and three touchdowns through his first two seasons. Adding that dynamic to his game would be a boost, but not one big enough to make him anything more than a middling QB2.
