Dre Greenlaw, a fifth-round pick from Arkansas, had a good preseason and earned a starting job with the 49ers. He hasn’t played a ton, but he’s been effective when he is on the field. Greenlaw’s athleticism came in handy chasing down Cardinals quarterback Kyler Murray for his first career sack.
DJ Jones got that play started, but Greenlaw flying in to knock down the quarterback was a terrific showing of speed from the linebacker.
