Nobody bashes Senna for a lucky set-up gamble in Monaco 1984.
Or Schumacher for Spain 1996.
Or (insert shit-load of race wins aided by the right set-up).
The cringe-worthy double standard is that for the entire history of Formula One discussions, wet races have been considered to be the true equalizer. That's where a driver can show his true talent.
But now that Vettel shows his skills in the wet (not only Monza), it is suddenly a lucky gamble.
*edit: pun not intended *
Compare Senna and Schumacher's wet weather form with Vettel at your own peril.
I cannot recall Vettel being labelled a "wet weather master" or "rainmeister".
As I said, there are many things to admire Vettel for, Monza '08 is not one of them.
