I was talking to a tennis statistician friend who has done work for tennis magazines . He’s watched all these guys and tracks the numbers. He made some of these observations about Borg.
“Think of it this way, in the 1981 U.S. Open, against Jimmy Connors, the speed gun had Borg hitting a serve that was the second fastest recorded in that tournament. I’ll see if I can find the clip. And obviously there were huge servers in those days.”
(see the 2 minute mark)
“They said Borg hit a 115 mile an hour serve and it was the second fastest in the tournament. And that’s with a wood racquet.”
“With today’s racquets, Borg could hit with far more pace and a much higher percentage on serve. The kids today have no idea. It’s recency bias. They assume everything today is the best. When I was a kid, I assumed that the odds were one of the players of the past had to be the best. Because of the law of numbers.”
“While I love Novak Djokovic, his weakness has always been his serve and overhead. It’s an excellent serve now but I’ve noticed that in pressure situations his first serve seems to desert him. It’s really not a natural motion. Borg’s was a much more fluid and natural player.”
“Djokovic has had times in the past we are he has served more doublefaults than aces for the year! It was a major flaw in his service motion where I believe he did not bring his racquet all the way back. Borg has never had that problem.”
“Don’t forget that wood racquets are much heavier and have less surface for spin. So with today’s much lighter racquets it’s easier to get much more racquet speed for power and spin. Borg had incredible racquet speed even with wood and let’s not forget the strings.” ( if you’ve never served with wood compared to todays frames you would have a hard time understanding this.)
“Arthur Ashe mentioned what an excellent serve Borg had at age 17! I also have some statistics that indicate that Borg led the ATP in percentage of holding serve AND Percentage of breaking serve”
“Incidentally in the early 80s during a match between Jimmy Connors and Ivan Lendl they had Lendl serving at slower speeds then Bjorn Borg with wood. And nobody accuses Lendl of having a slow serve. By the way don’t forget that Lendl had a graphite racquet.”
