This can't be possible. The #1 Toro Rosso seat has already been given to Rossi. At least according to his fans.
He may have plans for this year but plans change. As far as the F1 fraternity crushing him, that would remain to be seen. I think he is more talented than Speed who is no slacker. Also American drivers tend to not be taken seriously in F1 because the cream drifts to Nascar. As most "professionals", they go after the largest plum with the least obsticals.
