GLENDALE, Ariz. -- San Francisco 49ers coach Jim Harbaugh frantically sprinted down the sideline in the Sunday evening desert, trying to get one last timeout as the final seconds ticked toward overtime.He was on the mission of a coach trying to save his season. Or at least the No. 5 seed in the playoffs.It is Harbaugh's way to coach every game like it's his last. He has said it's a sin not to play like it's always on the line.
