There's no guarantee that Norwich will hack it in the Prem so it's really an impossible question.
Having said that Warnock has said himself that promotion has come too early. Perhaps we would have been better off a season later but who knows.
Having seen the average teams in the bottom half I think that perhaps if our recruitment had been a bit more savvy, we struggled for a right back, defensive mf and striker from the start, we would probably stay up.
