May I try to interject a few points here? What is the definition of skill in tennis anyway? Is it the mindless blasting away of groundstrokes that we often see today or is it something else? Tilden played in an era when small wooden racquets were the only thing available to them. In my opinion when you play with
small heavy wood racquets you can't just rely on power but HAVE to learn the finer points of the game. Where and when to position yourself when you hit a certain shot, varieties of spin and touch, how to volley better because you can't hit winners from the baseline, lobbing, changes of pace and angles are important.
Pete Sampras said that he would tell a player to use a wood racquet so he or she could learn the finer points of the game. I would tend to think Sampras knows more than most if not all of you.
Wood racquets enable players to learn more because they can't rely on blasting topspin groundies from the baseline or the ability to hit great serves on a regular basis. Tilden was an extremely gifted and skilled player and I don't understand why people should put him down. I guess it's the automatic reaction to BobbyOne writing Tilden is more skilled than Federer. However why should some of you put Tilden down to defend Federer? Just disagree and explain why Federer is more skilled.
Another point is this, we don't necessary have to have seen Tilden to know he was extremely skilled. The authorities who can attest to this are countless. Nevertheless I will point out that Ellsworth Vines, who was as objective a tennis authority as I have ever read wrote that he had never seen a player who could do as much off both sides as Bill Tilden. Vines wrote this in 1978 when he had already seen Laver, Rosewall, Kramer, Budge, Perry etc.
There was a story Fred Perry related in his superb book "Fred Perry, an autobiography." Apparently Tilden, who was playing a tour with Perry called Perry to hit with him in Kansas of all places. Here's a quote from the book-
-When we got to the court he asked me to hit a few to his forehand, low and wide. I did this and he returned them using a perfect continental grip, just as if he were mimicking my own forehand. When I inquired what he was up to Tilden said, "After playing so many matches against you and studying your style, I realized that the continental grip, and not my own Eastern grip, is the only one for that sort of shot. I felt I wouldn't be the complete tennis player unless I had mastered it to the stage where I could use it in a match if I wanted to." Tilden was 53 when that happened. It showed what a great analytical mind he had in tennis and how he was constantly trying to improve. Perry felt when he wrote the book that Tilden was the finest player he had ever seen and that Laver was the best after World War II.
In my opinion Tilden was one of the rare true geniuses in tennis history. We toss out the term genius too frequently nowadays. Without Tilden, tennis would not be the game it is today. Federer as great as he is uses many of the techniques Tilden used and perhaps invented. His book "The Art of Lawn Tennis" and "Match Play and the Spin of the Ball" influenced tennis players through the generations.
Do we call Einstein an idiot because he, as he was in his heyday couldn't use a computer if we transported him to today? Is Thomas Edison a lesser inventor because he didn't work for the big corporations of today? Is Leonardo da Vinci any less an artist or a genius because he can't operate a computer and use computer graphics to make his art better or to work on his many inventions? You all know the answer.
The question is asked "Who is the father of the modern game?" and I would venture to say that Tilden who could play the power game could be argued to be that. I don't think it's really a question whether Tilden would be great in today's game. It's a question of how great and awesome he would be. Tilden may play differently, maybe with a two handed shot, maybe he would play left handed but he would develop new theories about the game and the game would probably improve because of it.
Tilden incorporated so many of the strokes and techniques that we have in today's game that all of you who are decent players use them.
Here's a few videos of Bill Tilden. And I think he looks pretty good.

Here's a few facts for you. Bill Tilden won 138 of 192 tournaments from 1912 to 1930. His winning percentage was 93.6 during that period. This information is from the Collins Encyclopedia. From 1920 to 1925 he played only nine majors (I'm including the British Hardcourt which was the clay court major at the time) and he won all nine. Tilden in his best years, as Hoodjem wrote was reputed to have won 98% of his matches. He played Don Budge at age 48 and only lost 46 to 7 with one tie. Budge was at his peak at age 26. Tilden even defeated Ted Schoeder, who was the US Nationals Champion in the late 1940's.
I will also point out physically that Tilden was 6'2" with excellent mobility and footwork.
