I think it's safe to say that the wimbledon grass is playing much slower than in years past. We now see more rallies from the baseline and less serve & volley tennis. Patrick McEnroe even went out on a limb and said that he thinks the US Open courts play faster. One of things I've noticed with this current era is the lack of really GREAT servers. These guys like Nadal, Federer, & Djokovic are excellent all-around players. These guys are hitting shots that we've never seen before. However, I really think Sampras had much stiffer competition during his time, especially on grass. In addition, I think there were so many better BIG SERVERS he had to face. Ivanisevic, Rafter, Becker, Edberg (during his earlier times), Krajicek, Phillipousis, Michael Stich. In addition, there were great baseliners to contend with as well(ie Agassi, Courier, Kafelnikov, Rios, etc). What do you guys think? I don't doubt federer would've been #1 in any era. however is it safe to say that he would've had a tougher road to hoe if he had been playing in the 90s on the faster grass with the bigger servers?
