Prior to Syracuse, Shafer was an assistant at Michigan, Stanford, Western Michigan, Illinois, Northern Illinois, and Rhode Island. A 1990 graduate of Baldwin Wallace University, Shafer was one of Marrone's first hires.
Shafer's defenses have ranked among the nation's best in various categories during his four-year tenure with the Orange. In 2010, the Orange defense was No. 7 in the nation and he was nominated for the Broyles Award as the nation's top assistant.
Even though he won't be running the defense next season, Shafer doesn't expect the Orange to skip a beat.
"I envision an Orange crush defense that makes the opponents' families cringe when their child is about to get hit," he said with a smile. "I want to put the fear of God in the opposing football player that happens to have the ball underneath his arm. That's what we want to do, play an aggressive style of defense that people love to watch.
"When we get the opposition in the loud house (the Carrier Dome), we lock the doors behind them and we don't let them out."
