I don't think that this is the language of anyone making assumptions. I quite clearly leave open the possibility of there being information to counter what I am saying and also use the word 'decades', which to my mind is best used to describing a period of time ranging from 20 - 50 years.
I was actually responding to the following passage that you wrote:
"[...] tell me with a straight face that this isn't the most attacker friendly era in the history of Spanish football."
Which it factually isn't.
I never referred to the season that you and Brwned supplied stats for. I referred to the 1961 season when Pele scored 62 in 38 giving him his highest gpg ratio of 1.63gpg.
That said, thank you for posting the more in depth information on the Brazilian league, it sheds more light onto the easily accessible raw data. Care to share your sources?
I've carried out for some while research on some notable players throughout history, specifically on their appearance and scoring records (assists too where possible) and the competitions they played in. Incl. Pelé, Gerd Müller, Cruyff, Maradona of past greats, and Messi, Cristiano Ronaldo, Rooney of current players (also have the European records of Raúl and RVN).
For Pelé I've summarized the seasons 1957-1962 so far. The sources used include the book "Pelé: O Supercampeão" by Orlando Duarte (a sport journalist in Pelé's era), which details every goal ever scored by Pelé (incl. club friendlies) and RSSSF which details historic results of competitions.
My main point on Pelé is merely that his domestic stats are inflated because of the relative weakness of the
state championships (both by contemporary
and modern standards). That's not to say that Brazilian football was weak; it wasn't, as proven by its international success. Neither were they defensively inept as is often shouted about by the modern generation. It was simply a tactical climate perfectly suited for attacking football (the so-called 'W-M formation', a 3-2-5, still being in use, but especially 3-3-4s and 4-2-4s being popular in 50s/60s Brazil).
But back to my point:
*Pelé's career record in the Paulista (state championship of São Paulo): 412 apps, 470 goals (1.14 gpg). Mythical.
*Pelé's career record in inter-state/national championships (against the top teams of his own and other states): 193 apps, 119 goals (0.62 gpg). Impressive, but mortal.
His Copa Libertadores record is quite impressive as well (15 apps, 17 goals), but not unmatched by contemporaries like Alberto Spencer, José Sanfilippo or his own team-mate Coutinho. He was also only once top scorer in a season.
If there had been a real national league from the start of Pelé's career instead of at the end of it (1971), I highly doubt he would have maintained a scoring average similar to that in the Paulista.
