If you saw Singletary's hat-throwing fourth-quarter tirade when trying to call timeout in the 49ers' 25-22 loss to the New Orleans Saints, you know that rule is no longer operable.
"After the (Seattle) game I had several players and coaches (ask), 'Coach, you OK? What's wrong? You're not yourself," Singletary told Comcast SportsNet. "After the first game, I was biting my tongue and wrestling with myself and not to say this, not to say that."
