That has been the full expectation since the Bills selected Moss and allowed Gore to enter free agency. Devin Singletary showed well in 2019 but won't be asked to be a full-time three-down player in order to maintain his health. Moss didn't wow at the NFL Combine with a 4.65 40 his college film tells the story with his 4,000+ rushing yards and 38 touchdowns showing what he's capable of as a between-the-tackles runner. He does possess upside as a receiver as well if needed though Singletary is certain to be the primary weapon in that regard to start the season. As DLF's RB33, Moss has upside as a rookie and would be in for a large role should Singletary fall to injury.
