Derek Carr knew there would be growing pains adjusting to a new offense for the Oakland Raiders under coach Jon Gruden.
The surprising part for Carr and the Raiders is instead of showing steady progress throughout the year, the offense instead has regressed.
The Raiders (1-8) head into Sunday's game at Arizona (2-7) having gone back-to-back games without a touchdown for the first time since 2012, with the nine combined points in losses to San Francisco and the Chargers marking the lowest two-game output for Oakland since 2009.
"It gets frustrating because I know how hard some of our guys work and you expect it to continue to go this way," Carr said about the early season progress that hasn't been maintained.
