After taking four sacks, throwing an interception and being flattened by a forearm to the face, a sore but determined Derek Carr pulled out the kind of finish he wanted in his New Orleans Saints debut. Carr passed for 305 yards and a touchdown, and his 41-yard pass to Rasheed Shaheed on third-and-6 in the final minutes helped New Orleans run out the clock in a 16-15 victory over the Tennessee Titans on Sunday.
