From high-profile additions to NFL journeymen, The Bee provides a primer to the new players jockeying for position in training camp. Get to know the new faces at two position groups each day for both the 49ers and Raiders. Rosters are cut to 75 players Sept. 1 and 53 players Sept. 5.
Darren McFadden is now with the Dallas Cowboys after a single 1,000-yard rushing season in seven years with the Raiders, who had the NFL’s worst rushing attack last season.
Trent Richardson is still looking for his first 1,000-yard season since he was drafted third overall in 2009 by the Browns. The good news is he’s durable, having played no fewer than 15 games a season.
Key returner: Marcel Reece
Never miss a local story.
Key departures: Darren McFadden, Maurice Jones-Drew
Michael Dyer | 5-foot-9 | 218 pounds
Experience: Rookie (Louisville)
Last year: In nine games for the Cardinals, he rushed for 481 yards on 110 carries.
The skinny: Dyer had two 1,000-yard seasons for Auburn before transferring to Louisville for the past two seasons (following a suspension for a team rules violation). He can run, but he’s carrying some baggage.
Roy Helu Jr. | 5-foot-11 | 215 pounds
Experience: Five years (Nebraska)
Last year: He saw limited action for the Washington Redskins. In 14 games, Helu rushed for 216 yards on 40 carries. He also caught 42 passes for 477 yards.
The skinny: He was born in Danville, so this is something of a homecoming for the former Cornhusker. In four NFL seasons, he’s started just five games, so it’s likely he’ll be a Silver and Black backup.
Trent Richardson | 5-foot-9 | 225 pounds
Experience: Four years (Alabama)
Last year: He started 12 games for the Indianapolis Colts and totaled 748 yards from scrimmage and scored three touchdowns.
The skinny: Like McFadden, Richardson has yet to live up to expectations. Richardson has already had one change of scenery, so it’s hard to tell if this will be the one that flips his switch toward becoming the back who rushed for 950 yards and scored 11 touchdowns his rookie season.
