His first season, Temple had an OFEI in the 90's. Second season, OFEI had a big jump to the 50's. Keep in mind, a lot of them were not "his guys".
He's orginally from Coastal Carolina, so take a look at their film. The QBs and RBs in his offenses have usually put up really good numbers. There was one season where QBs and RBs were going down like flies, but the offense still produced.
