I thought they were going to warn and penalize excessive grunting at the beginning of the 2012 season. Here it is a year later, and grunting / shrieking is just as bad, if not worse. I seem to recall some dopey exception for the older players, as there's no way they could control or alter it (unless they're on the practice courts). So only the younger guard would be warned or penalized. I find myself either a. not watching matches with grunters; b. rooting for non-grunters; or c. muting the tv. I know I'm not alone.
