With the departures of Za’Darius Smith and Terrell Suggs this offseason, and with Matthew Judon likely to earn a big-dollar contract after next season, the Ravens need to embrace a new generation of pass rushers. Offseason surgery for a sports hernia has kept Walker’s stock from jumping, but he has a track record of success, if not starting, in the Southeastern Conference. As a reserve in 2017, he had 13½ tackles for loss and 5½ sacks in 15 games. Last season, he started and had 11 tackles for loss and 7½ sacks in 13 games, including a dominant performance against Alabama. At 6-2, 251 pounds, he has burst off the edge and a relentless motor, but scouts say his technique needs work, and he could struggle against more powerful tackles.
