Their top two pass catchers, Marquise Brown and Mark Andrews, delivered uneven seasons. Brown flourished in the playoffs, and Andrews remains a top-10 tight end. But the Ravens have not developed anyone else to scare defenses. Miles Boykin made a few big catches in the second half of the season, but Jackson simply doesn’t throw him the ball much, even when he’s open. Rookie Devin Duvernay vanished from the rotation down the stretch and never emerged as the vertical threat Harbaugh foresaw on draft day. With Hayden Hurst traded away and Nick Boyle injured, Jackson couldn’t rely on his non-Andrews tight ends. He’s yet to make much use in the passing game of future No. 1 running back J.K. Dobbins, who dropped an important third-down pass in the loss to Buffalo. Compared with other top teams, the Ravens lacked both downfield targets and bailout options to counter pressure.
