The splash signing for the Las Vegas Raiders on offense this offseason is quarterback Marcus Mariota as he is brought in to backup Derek Carr and compete for the starting job. Mariota was the unquestioned started in Tennessee for five seasons before being unseated by Ryan Tannehill who recently signed an extension with the Titans after leading them to the AFC Championship Game.
Mariota had his struggles in Tennessee but also managed to lead the Titans to the playoffs in 2017 and engineered an incredible comeback in Arrowhead Stadium against the Kansas City Chiefs.
