While it is difficult to predict the future, it would make sense for both the Oakland Raiders and Denver Broncos to move on from their leading pass catchers from 2017.
The Raiders owe Michael Crabtree over $7.5 million next season, per Spotrac, despite the fact he had just 58 catches for 618 yards and was essentially suspended two games (got ejected very early against Denver).
Crabtree was also rarely on the field late in the season. It is hard to tell who’s doing that was, Crabtree or the coaching staff, but it seems like Crabtree was wearing thin in Oakland.
