Blake Bortles, Brian Hoyer, Andrew Luck, and Marcus Mariota make up the likely starting quarterbacks for the 2015 season in the AFC South. The Jacksonville Jaguars and Indianapolis Colts have the position nailed down, with Luck looking like a future Hall of Famer and the Jaguars forging ahead with Bortles after a rough rookie season.
For the Texans and the Titans, things could still shift. The Texans opted to go forward with either intriguing Brian Hoyer or unproven Ryan Mallett at the helm of what could be a playoff team and the Titans have their QB of the future in Mariota, though 2014 starter Zach Mettenberger doesn’t intend to relinquish his role without a fight.
