A 2014 sixth-round pick out of LSU by the Tennessee Titans, former NFL quarterback Zach Mettenberger got a good number of opportunities to play early in his career due to injuries to those in front of him. Perhaps things would have gone better for him if he were not thrust into that level of responsibility.
He started 10 games in his first two years and lost all of them. He ended up being let go twice over the course of the offseason o 2016, eventually landing with the Pittsburgh Steelers, who claimed him off waivers after backup Bruce Gradkowski suffered another season-ending injury.
