I think Derek Carr’s career has been an enigma. The consistently poor quality of the teams he’s played on have been an enigma. He has played on a lot of bad teams and for bad coaches.
One of the only times in his career when he had solid help surrounding him and healthy, he finished third in MVP voting.
He’s had a strange career arc with unprecedented levels of ineptness surrounding him.
The mere fact that those Raiders teams couldn’t take a “fairly competent”/“decent at worst in his prime” QB like him to the playoffs more than once over such a long period of time points more towards organizational ineptness than a QB problem, JMO.
Just take a look at the Raiders defensive rankings during his time there, for starters.
