Born in Woodland, California, Wulff graduated from Davis Senior High School in Davis in 1985. He accepted a scholarship from head coach Jim Walden to attend Washington State University in Pullman, and redshirted his first year in 1985. Wulff started four games at guard for the Cougars as a redshirt freshman in 1986. Later a center, he was a starter on the offensive line from 1986 to 1989 under three different head coaches: Walden, Dennis Erickson, and Mike Price. During his junior year in 1988, the Cougars were led by Erickson and quarterback Timm Rosenbach, and scored an upset over top-ranked UCLAon the road, the first of five consecutive wins to close out the season. WSU tied for third in the Pac-10, and won the Apple Cup and the Aloha Bowl. It was Washington State's first bowl game in seven years and their first post-season victory in 63 years, since the Rose Bowl in January 1916. WSU finished at 9–3 and sixteenth in both major polls. In his senior year under Price, the Cougars won six of their first seven games and were ranked fifteenth in mid-October. After two close losses, Wulff had an emergency appendectomy on Halloween and missed the final two games, both defeats, and WSU finished at 6–5 with no bowl. Following graduation in 1990, Wulff signed as an undrafted free agent with the New York Jets of the National Football League, but was released during the 1990 preseason. During the spring of 1991, he played for the Raleigh–Durham Skyhawks in the newly created World League of American Football. The team went winless in its inaugural season and was folded. Wulff continued to play for another season in the league with the New York/New Jersey Knights, before ending his active career.
Coaching career
Wulff began his coaching career in 1993 as a volunteer assistant under head coach Dick Zornes at Eastern Washington University in Cheney. Zornes retired after that season and assistant coach Mike Kramer was promoted to head coach, who hired Wulff to a full-time position. After four seasons as the Eagles' offensive line and strength coach, Wulff added offensive coordinator duties in 1998. When Kramer departed for conference rival Montana State after the 1999 season, the school named Wulff his successor. During his eight seasons as EWU's head coach, Wulff compiled an overall record of 53 wins and 40 losses; the Eagles won two Big Sky Conference co-championships and appeared three times in the Division I-AA playoffs. Wulff earned Big Sky Coach of the Year honors in 2001, 2004, and 2005. Wulff returned to his alma mater after the 2007 season when he was named the 31st head football coach at Washington State on December 10. He was the second alumnus to head the Cougar football program, after Phil Sarboe in the late 1940s. After compiling a 9–40 record during four losing seasons at WSU, Wulff was fired on November 29, 2011, and left with the lowest winning percentage in school history. His teams only won four games in Pacific-10 Conference play, including a winless 0–9 conference mark in 2009—part of an overall record of 1–11, the worst in the school's modern football history. In May 2012, Wulff joined former Pac-10 foe Jim Harbaugh as an offensive assistant with the San Francisco 49ers, with multiple duties on that side of the ball. In January 2014, he was hired as the offensive coordinator and offensive line coach at the University of South Florida in Tampa.
Personal life
Wulff met his first wife Tammy Allen at WSU and they married in 1993. Diagnosed with inoperable brain cancer in early 1997, she battled for over five years, but succumbed in March 2002. As a youth, Wulff's mother went missing and was never found. The youngest of four children, he went to live with relatives, first with an uncle, then with his oldest brother. Wulff and his wife Sherry have three children.
