That season the Wolves won the 2002 Calder Cup, with Nardella accumulating 14 points. After six consecutive seasons with the Wolves spanning from 1997 until 2003, Nardella was released by the team on January 28, 2003, and he subsequently joined the Milano Vipers in Italy and played two games for the Quad City Mallards in the UHL.

His uncle Mike worked for the Chicago Blackhawks organization and his cousin Frank played NCAA hockey for Dartmouth College. While living in Rosemont with his wife Alicia, Nardella's elder son Bobby plays NCAA hockey for the University of Notre Dame and his younger son Nicholas played in the North American Hockey League.
