Although Vanderbilt and Stanford have not offered official word, David Kotulski provided confirmation via Twitter that he is the Commodores’ new defensive coordinator. The following message was posted on Kotulski’s account @CoachKoto: “I’m very excited to accept this challenge to be the defensive coordinator and help Coach Mason take Vandy from Good to Great!” Kotulski also thanked Stanford and called Vanderbilt coach and former Cardinal defensive coordinator Derek Mason as a great friend. Kotulski, an Illinois native, has 36 years of college coaching experience across seven schools. He spent the last two seasons instructing inside linebackers at Stanford, including All-American Shayne Skov. Prior to that, Kotulski was defensive coordinator at Lehigh for six seasons. His 2011 defense was among the best in the Patriot League in virtually every category, and his 2009 defense led the nation in sacks with 39. Kotulski’s career also featured an eight-year stretch (1995-2002) as defensive coordinator and linebackers coach at Bucknell, where he also served as interim head coach in 2002. His other stops included: Utah (1978-89), Saint Mary’s (1990-94), Utah State (2003-04) and Holy Cross (2005).
