I think you have seriously underestimated the worth of all time record and legacy here. Regardless of how you rate those players having watched them played week in week out, in future, for those who were born after us, they wouldn't care too much about how good the players from their grandpa era actually were, but they would be always reminded of those who are GOAT or all time greats, or those with the records.
Take Fontaine for example, he hasn't won any major trophy throughout his career, nor did he score alot throughout, but he is still being remembered even today, because of his record in 58 WC. I am sure there were lots of better strikers than him during that time, but people could only remember him above the others (non-elites), who might be better than him, just because of his records.
I mean, just look at his overall career, he scored 227 goals in his club career in 12 years (average 19 goals per season). His overall numbers are actually similar to Klose. Then for France he scored 30 goals in 21 games overall, where 18 goals are scored in 1958 alone. He only have a truly extraordinary year in 1958 WC in terms of goalscoring, before that he only has 3 goals in 3 caps over 5 years period of his international career, and after that in the next 2 years period he managed another 9 goals in 6 games, and his career ends there. Theres nothing, apart from 1958 WC, or during period 1958-1959, to suggest he is a great player at all, yet he is still regarded as football legend, as was often named as best 100 players ever played the game. Truth is, no one would remember him if not for his record in WC, its plain obvious.
