Now what's being said is "Even big shots can make mistakes." Before it was said they were all little shots. For an inept con man, Rossi sure seemed to maneuver around plenty of big shots and little shots.
Focardi was a good researcher in his time. Levi is a little shot. Looking at his CV I don't really understand how he attained tenure and after 20 years on faculty he is still at the lowest rank of assistant professor. His research is unimpressive and he does not seem to supervise any graduate students. He has value as a teacher, but not in his own department.
Rossi is a con man, but not inept. He is good at it.
