The fifth-round rookie has been excellent in his first season, and will have a couple tough assignments against Green Bay. He’ll be tasked with covering running back Aaron Jones on some snaps, and he’ll have some matchups with tight end Jimmy Graham. Greenlaw has been a valuable linebacker as a run stopper and in the passing game, and that has to continue Sunday. Not letting the Packers successfully isolate him on the running back or tight end keeps the 49ers from warping the rest of their defense to help the rookie linebacker.
