The 2020 NFL draft is in the books, but that doesn't mean teams are finished adding rookies they hope will be able to contribute on the field next season.
Undrafted free agents have become a luxury that all 32 organizations have taken advantage of. San Francisco 49ers running back Raheem Mostert went undrafted out of Purdue in 2015 to setting a franchise playoff record with 220 rushing yards in the NFC Championship Game against the Green Bay Packers.
In the Kansas City Chiefs' 31-20 Super Bowl LIV win over the 49ers, undrafted Damien Williams ran for 104 yards and scored the decisive touchdown with 1:20 remaining.
