ALAMEDA, Calif. (AP) — Derek Carr's career was on a clear upward trajectory his first three seasons before a broken leg in the second-to-last game in 2016 ended his season, and any hopes the Oakland Raiders had of competing in the playoffs that year. The leg took a few months to heal, but Carr hasn't been the same quarterback since, even with the coaching change that brought Jon Gruden to Oakland. While the Raiders (1-5) head into their bye week with a litany of problems from a lack of a pass rush to a broken-down offensive line to a spotty secondary, Carr's struggles this season are near the top of the list. Gruden returned to coaching in part for the chance to coach Carr and was being counted on to get the best out of the quarterback the Raiders rewarded with a $125 million contract less than 16 months ago.
