Ryan Tannehill #17 of the Miami Dolphins looks to throw a pass during the first half against the New England Patriots at Gillette Stadium on September 30, 2018 in Foxborough, Massachusetts.
The Dolphins will receive a fourth round pick in 2020 and a seventh rounder in 2019 while the Titans will also acquire a 2019 sixth rounder along with Tannehill.
Tannehill, in all likelihood, was going to be released by the Dolphins this offseason, pending what they could figure out in the quarterback market. Miami's current depth chart is Jake Rudock and Luke Falk.
Teddy Bridgewater, an injured Miami Northwestern High graduate whom the Dolphins had courted, signed this week with the New Orleans Saints. The hashtag #tankfortua has become popular as some teams reportedly ponder intentionally losing games next year to gain a good spot in the NFL Draft when Tua graduates.
For the Titans, this is a high-end move but a smart one. He's also battled injuries for nearly all of his career, and the Titans have struggled when Mariota has missed time. Both have had minimal playing time under center.
