No great driver is ever replaced, they simply fade away... someone arrives and maybe is just as good, maybe better. How can you tell? The cars and rules change from season to season. Would Schumacher have beaten Fangio? Hamilton ever beaten his hero Senna? We don't know. There are enough idiots running F1 and far from seeing it as a sport, without we fans joining in. Schumacher deserves his place among the greatest but let's hope others will join him there.
