The Las Vegas Raiders could have one of the most intriguing quarterback battles when training camp opens ahead of the 2020 NFL season.
The relocated franchise brought in Marcus Mariota during free agency to compete with Derek Carr, who has been the starting quarterback since 2014.
According to ESPN's Jeremy Fowler, the Raiders "kept all options open at quarterback" before finalizing a deal with Mariota to back up Carr.
Fowler also noted that he believed the Raiders were one of eight teams to inquire about Tom Brady before he landed with the Tampa Bay Buccaneers.
