The 49ers look to replace the franchise’s all-time leading rusher (Gore) with more than one person. Carlos Hyde is best-suited to be the back on base downs and short-yardage situations. Reggie Bush, a free-agent pickup, and Kendall Hunter can play base downs behind Hyde, but they might be better-suited as third-down backs.
Hyde is expected to take over as the team's primary ball-carrier, with Bush assuming the passing down role. Given Bush's presence and Hyde's 4.0 YPC during in his rookie season, Hyde's upside may be somewhat limited. Expect 250 or so carries and a limited role in the passing game. That may be his ceiling with Bush (along with Kendall Hunter and rookie Mike Davis) eating away at his snaps.
