QB Spencer Rattler is a strong candidate to start in Derek Carr’s absence, sources tell Garafolo and Rapoport

My point is that they never gave the #2 job to anyone officially, just different roles while they shared the second team QB slot on the depth chart. We have no 3rd team QB.

Technically they did because Haener is #2 and rattler has been scout team. all that other nonsense is just coach speak.
