Also, from the bio...
"As secondary coach, Rhoads had five players taken in the last six NFL drafts, including
2006 Thorpe Award Finalist Darrelle Revis, who was the first secondary player selected"
Sounds like (from the Pitt website) that Rhoads also coached the secondary in addition to his duties as DC, and he moved to personally coach the linebackers later on.
I also noticed that Pitt in his final season there was #5 in total defense and #3 in pass defense, and the Big East had some VERY high powered offenses that year. Proven success, only thing worrying me is the lack of hc experience.
