Running back Brandon Jacobs has retired from the NFL so he doesn’t have to worry about remaining in the good graces of anyone who might think about hiring him in the future.

Or anyone who hired him in the past, for that matter. Jacobs spent a frustrating 2012 season as a member of the 49ers that saw him spend most of his time on the inactive list before getting suspended for conduct detrimental to the team. Jacobs, who was released at the start of the 49ers’ playoff run and returned to the Giants in 2013, had tweeted something about hating your boss before his suspension.

He said at the time that he wasn’t talking about 49ers coach Jim Harbaugh and insisted during a Thursday interview on WFAN that he was always respectful toward Harbaugh while he was in San Francisco, but retirement seems to have loosened his tongue.

“He is a bitch, and that’s why he’s never won anything,” Jacobs said. “It is what it is. I’ve got two rings. Harbaugh, though, he’s a bitch. So it doesn’t matter.”

Jacobs frequently shared exactly what was on his mind during his Giants career, whether through his comments or through a toss of his helmet. It doesn’t look like he’ll be changing course now that he’s hung up that helmet.
