LB Dre Greenlaw
It’ll be interesting to see how Greenlaw’s role shakes out in 2020, but he performed very well as the Will linebacker after Kwon Alexander went down with a torn pectoral in Week 9 last year. He was graded as the 49ers’ best tackling linebacker by Pro Football Focus, and allowed the second-best passer rating among 49ers linebackers when targeted in coverage. He showed the ability to be effective on all three downs, and his rookie year could be enough to push him into the Will linebacker role with Alexander taking on the Sam linebacker spot in the base defense.
