Hacking. Paul Johnson, M.D. and coach at Georgia Tech, read the diagnostics quickly enough in firing Al Groh six games into the season. Clearly a fan of amputation, Dr. Johnson performed the operation after the Georgia Tech defense gave up more than 40 points in three straight games. This stretch included a 49-28 loss to Middle Tennessee State, whose only other 40-point game came against Memphis. This alone justifies the amputation. Proceed with your practice, Coach Johnson.
