SANTA CLARA, Calif. -- Nothing can ruin a road game like an offense losing the ball.The San Francisco 49ers are acutely aware of turnovers this week as they prepare to play at the Tennessee Titans on Sunday. The Titans have a swarming defense. 49ers coach Jim Harbaugh said Wednesday the group can cause turnovers in a hurry."[They are] probably the best team we've seen at stripping, clubbing, punching the ball out, creating turnovers, very physical," Harbaugh said.
