Dre Greenlaw

Greenlaw missed three games due to injury last season but still nearly matched the impressive totals from his rookie campaign, going for 86 tackles and a sack after 92 and one, respectively, in 2019. Kwon Alexander was shipped to New Orleans midseason, due in large part to Greenlaw's impressive play while filling in as the starter at the Will position. The 24-year-old is all but a lock to start at that same spot alongside middle linebacker Fred Warner this upcoming season.

The 49ers found a diamond in the rough when they selected Dre Greenlaw in the fifth round of the 2019 draft. The 23-year-old beat out veteran Malcolm Smith for the Sam linebacker job in camp, and the rookie flourished in an every-down role when Kwon Alexander suffered a torn pectoral Week 9. Greenlaw finished with 92 tackles (64 solo), a sack, an interception and two passes defended through 16 games, with his most notable play being a goal-line stop on the final play of the regular season to seal the victory - and division title - over the Seahawks. The sophomore linebacker will have a starting job to begin the 2020 campaign, but the question will be whether he or a healthy Alexander occupies the starting Will position alongside Fred Warner. If Greenlaw is moved back to the strong side, then his IDP value would take a significant hit.
