49ers GM Trent Baalke insists RB Marcus Lattimore (knee, hamstring) has not suffered a setback. Lattimore has missed the first three days of camp after being limited in spring workouts. "He's coming off, as we all know, a horrific injury," said Baalke. "... But as far as setbacks, no." We remain highly skeptical Lattimore will make any 2014 impact. With Kendall Hunter (ACL)) already lost for the season, rookie Carlos Hyde and Frank Gore are the 49ers' fantasy backs to own.
