Found a fascinating challenge match, in which Jimmy Connors beat Rod Laver, 6-4, 6-2, 3-6, 7-5 at Caesars Palace in Las Vegas, February 2 1975. The footage is a video camera pointing at the TV – but you can see the shots surprisingly well.
As the (excellent) comment thread points out, Laver was well over the hill at this point (whereas Connors was Wimbledon champion), but you get a sense for why many regard Laver as the greatest ever. Even here his movement (especially at the net) is phenomenal, and for all that his technique sometimes looks odd to modern eyes (where is his front arm on the forehand groundstroke?), the power and placement is there, even with those crappy old rackets.
