But the courts were faster back then. That would have made a huge difference to the aces/1st-serve points???
As
@TheFifthSet keeps telling you this is a myth that refuses to die. Three S&Vers made the SFs at '01 Wimbledon,
its 1st edition with the new "slow" grass, and
other '90s holdovers also did quite well there with their supposedly outdated style well into the '00s. And every service stat but DF has been creeping up ever since. Even if the courts are indeed slower today - which has never been proven, BTW, contrary to the endless talking points - it's undeniable that the extra spin from today's sticks has more than compensated for the slowdown factor.
Arthurs had a reasonable ground/net game. If his serve was on Kyrgios’ level he would have had a better overall career imo
Kyrgios is easily top 5 on the tour over the past 6/7 years along with Karlovic, Isner, Opelka, Roanic
You've got it exactly backwards. While Nick's ground game is usually nothing to write home about he still wins 15.8% of his (career) return games, vs. Arthurs' rock-bottom 10.0% which is Groth/Isner/Opelka territory (10.4%/10.3%/10.0%) and just barely above Karlovic's 8.5% (the absolute lowest since '91 and probably in the entire OE). To put this in perspective that 5.8% gap is about the same distance between Fed (26.6%) and Roddick (20.3%), with of course 19 majors separating the two.
And even your last sentence is debatable. Kyrgios having played almost 3 times as many 1st-serve points as Groth would seem to indicate that he's faced more top opposition, and the ATP indeed tells us they faced off against top 10 players 37 (winning 21) and 9 (losing 'em all!) times respectively. But then compare Nick's 21-37 vs. the top 10 with these guys' records, followed by % of matches vs. the top 20 (expanded cuz rankings were rather unreliable before the current standardized era)*/all career matches:
Federer - 223-123 (64.6%), 542/1556 (34.8%)
Isner - 28-74 (27.5%), 165/740 (22.3%)
Raonic - 30-67 (30.9%), 146/547 (26.7%)
Anderson - 19-72 (20.9%), 151/597 (25.3%)
Querrey - 23-66 (25.8%), 168/700 (24%)
Karlovic - 21-62 (25.3%), 143/717 (19.9%)
Kyrgios - 21-37 (36.2%), 85/271 (31.4%)
Muller - 12-44 (21.4%), 99/446 (22.2%)
Opelka - 7-10 (41.2%), 33/130 (25.4%)
Groth - 0-9 (0%), 20/100 (20%)
*TA's stats for active players aren't completely up to date, but the %s of career matches vs. the top 20 matches shouldn't be far off the mark. Also I would've liked to expand the range to top 30 cuz of the specialization factor of yore - FYI Rafter was ranked only 21st going into '00 Wimbledon, which everyone knows did not reflect his true standing on grass - but TA's next option is top 50 which is too large.
Now Nick's 31.4% vs. the top 20 is well above the average for his fellow servebots - which does reinforce the widespread view that he's got more upside and wasting his talent - but still clearly below Fed's 34.8%. And how does he compare to previous GSOAT candidates? Let's see:
Sampras - 124-71 (63.6%), 336/984 (34.1%)
Ivanisevic - 60-76 (44.1%), 236/932 (25.3%)
Roddick - 37-73 (33.6%), 189/825 (22.9%)
Ljubicic - 40-70 (36.4%), 183/725 (25.2%)
Krajicek - 44-54 (44.9%), 164/630 (26.0%)
Philippoussis - 24-52 (31.6%), 128/517 (24.8%)
Arthurs - 8-23 (25.8%), 56/292 (19.2%)
Johansson, J. - 4-7 (36.4%), 23/131 (17.6%)
As you can see every one of these guys but Wayne and Pim Pim played top 10/20 guys more often, and it's probable that the average ranking of Nick's opponents is higher, especially given his inconsistency. And Pistol's % vs. the top 20 still beats Nick's by almost 3 percentage points, which is hardly surprising given their career trajectories.
That's why Fed features on
my definitive GSOAT list while Kyrgios doesn't. As a pure shot Nick's serve is most likely better, but that don't mean a thing unless he can swing it when necessary and that's where Fed comes out on top. And get this:
Sampras won an average 45% of his serves as outright freebies in his 18 Slam finals (47% if we take only the 14 finals he won). Hard to imagine Kyrgios coming anywhere close to that under pressure vs. similar opponents.
Now you could say, not unfairly, that this logic doesn't apply to Arthurs, but his 6.4% lead in the freebie department is just too big to be explained away by pointing to Nick's superior opposition. Plus it's no coincidence that both Wayne and Goran are southpaws whose lefty spin helps offset Ivo's considerable size advantage. And say what you still about Karlovic's serve but disguise isn't one of his strengths. Arthurs', OTOH, is among the most unreadable ever (if perhaps not quite in Goran's class), and while Nick is no slouch himself he must yield to his countryman here.
