Lol @ primes clashing. The revisionist shyt.
I disagree.
There are late bloomers and gifted youngsters, and those players may end up "clashing" more than others between generations.
Ok lets check for Best players in a 10 years age gap
Gen 1 born 1971 : Sampras, Turned Pro 1988, won 2nd slam 1993
Gen 2 born 1981 : Federer, Turned Pro 1998, won 2nd slam 2004
Gen 3 born 1991 : Dimitrov, Turned Pro 2008, Never won 2nd slam but ideally would have around 2014 if he was an ATG, but his generation were untalented morons.
Gen 4 born 2001 : Sinner, Turned Pro 2018, will win his second slam around 2024, this will happen
So this lost generation you talk about are the guys born from late 80s till late 90s, more like CIlic's birth year till Medvedev's birth year, 1988 till 1996, around 9 years.
Sinner will win slams like Federer/Sampras/Novak before him because he is not lagging behind in age related metrics.
Age when a player entered top 10 :
01. Nadal - 18 years 10 months
02. Sampras - age 19 29 days
03. Novak - 19 years 9 months
04. Sinner - 20 years 1 months
05. Federer - 20 years 9 months
Before Sinner if we go down birth years for top players yearwise from 1989-1998
Felix born in 2000 reached at 21
Stefanos born in 1998 reached at 20
Zverev born in 1997 reached at 20
Medvedev born in 1996 reached at 23 years 5 months
Thiem born in 1993 reached at almost 23
Dimitrov born in 1991 reached at 23
Nishikori never reached top 10
Conclusion : Nature gifted Federer with a sweet spot of no ATGs 10 years before him and 5 years after him with none in his own age group, so to correct this nature produced 2 ATGs 5-6 years later quickly .... this was to balance mistake done for 15 years, but that created further imbalance which made players born in 90s losers .... now from Sinner onwards Nature will correct itself again as natural balance will be restored when new ATGs will come in 2 years time.
Medvedev is like Hewitt, a transitional champ between eras who beat 9-10 years older ATG because of age advantage..... real ATGs will arrive in near future, possible Sinner will be that or someone will mature quickly in next 12-18 months..
