Tannehill's time in Miami was coming to a close with a new regime in place. And his departure doesn't come as a big surprise when considering reports surfaced that the team was expected to go a different direction at the quarterback position under head coach Brian Flores.
Tannehill entered the league in 2012 as the eighth overall pick with the Dolphins, but he never lived up to his lofty draft status. He posted a 42-46 record over six seasons, while throwing for 20,434 yards and 123 touchdowns with 75 interceptions.
He departs Miami with a career 62.8 completion percentage and an 87 passer rating, and left money on the table. Before the trade, Tannehill had two years remaining on his contract and would've been paid a base salary of $18.7 million in 2019 and $19.4 million in 2020.
A fresh start, though, could work out for Tannehill, who turns 31 on July 27, as he won't have the pressure typically associated with a starting quarterback.
Mariota is currently the Titans' franchise quarterback and Tannehill projects as Mariota's primary backup.
Gabbert was previously Mariota's backup and started three games in 2018 when Mariota was injured. His one-year stint came after one season in Arizona, three in San Francisco and three in Jacksonville, which selected him 10th overall in the first round of the 2010 draft. Gabbert is the second former Jacksonville first-round selection released this week after Blake Bortles was cut by the Jaguars on Wednesday.
