Browns coach Eric Mangini regrets hinting that he felt the Lions faked injuries during Sunday's game. Detroit defeated Cleveland 38-37 on a last-second touchdown pass that was set up by a pass interference call, which Mangini also questioned. "At the end of the day we're accountable for losing the game and for not making enough plays," Mangini said. "That's me, that's the coaches, that's the players. That's what it was. I think I was frustrated with the situation and probably expressed that more than I probably should have, but at the end of the day we're responsible for it. "We had plenty of opportunities to win the game and we didn't. That wasn't good enough," he said.
