Tiki Barber has been Tom Coughlin's biggest critic, but after yesterday's 27-13 victory over the Panthers broke a four-game losing streak, he endorsed the coach's return in 2007 and insists Coughlin deserves a contract extension. The vote of confidence came from an unexpected precinct, considering Barber publicly questioned Coughlin twice over the last 11 months. But he firmly said, "I do," when asked if he thinks the Giants should bring Coughlin back. "He's done a good job," he said, standing outside the Giants' locker room. "He's been here for three years and been riddled with major, major injuries and he's held us together."
