There are certain posters saying that players like Sampras, Becker and Ivanisevic would have been clocked as serving at 140mph/150mph if they were clocked by today's speed guns that measure the speed of the ball as it leaves the racquet. My memory is that the new speed guns came in around the year 2000 and that it only added around 7-8mph to players serves. And quite a few players like Sampras and Agassi played under the new speed guns and din't serve much faster. EG Sampras went from the 115-128mph on first serves to 122-135mph, Agassi went from 105mph-115mph on first serves to the 112-122mph range. Is my memory letting me down or are some forum members delusional teenagers pretending to be older than they are?
