During their years of being fit enough Ronaldo and Messi have been exceptional and never have dropped from the top. What's Hamilton's excuse?
So if someone like Lewis Hamilton, who like it or not has a tremendous record, cannot be considered a GOAT contender, who should?
Let's consider some of the contenders named in this thread:
Fangio - 2, 1, 2, 1, 1, 1, 1, 14
Surtees - 14, 12, 4, 4, 1, 5, 2, 4, 7, 11, 18, 18, 19, UC
Clark - 10, 7, 2, 1, 3, 1, 6, 3, 11
Senna - 9, 4, 4, 3, 1, 2, 1, 1, 4, 2, UC
Schumacher - 14, 3, 4, 1, 1, 3, DQ, 2, 5, 1, 1, 1, 1, 1, 3, 2, 9, 8, 13
Vettel - 14, 8, 2, 1, 1, 1, 1, 5, 3, 4, 2, 2, 5, 13, 12
Hamilton - 2, 1, 5, 4, 5, 4, 4, 1, 1, 2, 1, 1, 1, 1, 2
Fangio, finished his last season 14th - what's his excuse?
Surtees, multiple seasons where he didn't even hit the top ten - what's his excuse?
Clark, an also ran in his first season and died in his last - not very GOAT is it?
Schumacher, disqualified and a midfielder for the last 3 years. So much for him!
Vettel, languishing outside the top 3 for years now, never a GOAT contender.
Senna, died at the wheel, doesn't sound like the sort of bloke who should be considered a GOAT if he couldn't even keep it on the tarmac.
Actually, on pure numbers in terms of average championship positions (not having done any actual maths) Fangio, Senna and Hamilton seem to be by far the best performers from that lot.
EDIT - just because people have a hard time dealing with sarcasm in this forum, I'd like to point out that Fangio, Surtees, Clark, Schumacher, Vettel, Senna and Hamilton are clearly all fantastic drivers who were at the top of their game for considerable periods.
