Under Rodgers, San Francisco led the NFC and was second in the NFL in net punting as NFC Pro Bowl honoree Andy Lee averaged 47.3 yards a kick and netted 41.0 for the year. The 49ers became just the second team in NFL history to net 40-plus yards a kick during a season, while Lee and the 49ers also set the NFL record with 42 kicks being downed inside the opponent's 20-yard line.
Rodgers joined the 49ers staff from the University of Arizona, where he spent two seasons as a graduate assistant on defense in 2002.
He played four seasons at linebacker for North Texas where he earned his degree in business, specializing in entrepreneurship and strategic management in 2000.
Ruggiero, a 20-year coaching veteran, helped develop Scott Riddle into one of the top freshman quarterbacks in the country averaging 347 passing yards with 31.5 completions per game. Riddle was second in the nation in passing yards with 3,817, and third in total offense at 340 yards per game.
Prior to his arrival at Elon, Ruggiero spent the previous six years at Hofstra, serving the first two seasons (2000-01) as the recruiting coordinator/quarterbacks coach and the last four (2002-05) as the offensive coordinator.
Other coaching jobs were at The College of William and Mary during the 1999 campaign, plus Glenville State, Clarion University, The Defiance College and University of Delaware.
An offensive coordinator at five colleges, Ruggiero's offenses have finished among the country's top 10 teams and also has coached a quarterback to All-America status at all five stops.
