The "fever" is because several QBs who were so-called no-names in college, among them Messrs. Brady, Roethlisberger, Warner, and Flacco, have had some success in the NFL, prompting everyone to look at under-considered QBs as the future of the team. Cf. the early 90s, when everyone had to be into some no-name grunge band.
As for LeFevour, I think you underrate him somewhat; he'd be a good fourth-round pick, and maybe a decent third-round pick.
