Couldn't disagree more.
1. Cycling is about far more then wins, otherwise nobody would remember Poulidor. Pozzato hasn't won an awful lot since MSR, but nobody can deny he is a great classics rider. Same argument with Hincapie. E3 was Cancellara's first win in Belgium, but he had the reputation as a top class rider long before. Winning is important, but there are superb riders around who haven't managed to pull off that many wins.
By your logic, Zabel counts as a great, but somehow Boonen does not. Who is more revered amongst fans as a classics rider? Easy question, it ain't Zabel. Super as he is.
2. Your list is a bit odd, Zurich but no Fleche? Only one of those races still exists
And Amstel is at least as prestigious as Zurich. Plus Paris Tours is cool and all, but if that makes your list Gent Wevelgem has to as well.
