Rapoport reported prior to the start of the season that Harbaugh "may already be losing some players."
According to Rapoport, players are upset Harbaugh "kind of treats them like children." Players are not allowed to listen to music or play cards on plane rides, Rapoport reports.
Harbaugh's contract runs through the end of next season, and the 49ers front office has put off extension negotiations until at least the end of this season.
