ESPN Fantasy Projection: Expectations generally aren't very high for sixth-round rookies, but Mitchell quickly took control of San Francisco's lead-back gig last season and -- injuries aside -- never gave it back. Including the playoffs, Mitchell appeared in 14 games and carried the ball at least 17 times in 11 of them. He was a top-20 fantasy back in seven of 11 regular-season outings, though his output was limited by a lack of goal-line work (six TDs and four carries inside the 5) and limited passing-game work (20 targets). Nothing about Kyle Shanahan's offense suggests we should expect a major change in role, and new QB Trey Lance may actually steal even more goal-line work. Mitchell's heavy rush volume keeps him in the back-end RB2 mix, but his ceiling is limited.
