Claim:
1. A football sensing system comprising: an American-style football extending along a longitudinal axis and having a maximum transverse dimension defining a transverse axis; at least one accelerometer carried by the football to sense acceleration of the football along at least a first axis, the accelerometer sized to sense a predetermined maximum value of acceleration in the first axis, the accelerometer being positioned within the football in a first position with the first axis of the accelerometer angled with respect to the longitudinal axis of the football, the accelerometer in the first position being capable of measuring acceleration values in a direction in line with or parallel to the longitudinal axis of the football that are greater than the predetermined maximum value of acceleration in the first axis, the at least one accelerometer being spaced apart from the longitudinal axis such that the at least one accelerometer can measure centripedal acceleration of the football.
