What It Means:

Singletary has been charted with two fumbles in "only seven padded practices and not a whole lot of team drills and rushing attempts." This isn't a new problem, as Singletary had the highest fumble rate in the league at his position last season. Meanwhile, third-round rookie Zack Moss continues to garner praise. All signs point to the Bills wanting to use a committee approach, but Moss could emerge as the preferred backfield option over last year's third-rounder.

numberFire's models project Singletary for 175.3 carries, 777.4 rushing yards, 228.2 receiving yards, 31.2 catches (44.3 targets), and 6.4 touchdowns this season. He's the RB27 in our preseason fantasy rankings. Moss is projected for 132.2 carries and 22.3 receptions (31.7 targets).
