The Las Vegas Raiders will have a training camp battle on their hands to determine who will back up Derek Carr in 2022. There was a new brain trust that took the reins this offseason for the Silver and Black. This new duo, led by new general manager Dave Ziegler and head coach Josh McDaniels, immediately made their presence known by bringing in new coordinators, acquiring several new key players, and also moving on from other contributors. Among those that are no longer around is Derek Carr’s backup for the last two seasons, Marcus Mariota.
