Sean Spencer "Coach Chaos"
Sean Spencer is in his first season as the Nittany Lions' defensive line coach. Spencer has experience on both sides of the ball and special teams during his 18 seasons as a collegiate coach, but he has been exclusively helping build strong defensive units since 2001. During his 2011-13 tenure at Vanderbilt, Spencer's defensive lines helped VU finish in the Top 25 in total defense all three years. The Commodores recorded 28, 31 and 28 sacks the past three years, with the D-Line posting 42.5 tackles for loss in 2013. Spencer mentored defensive end Caleb Azubike, who set a Vanderbilt true freshman record with four sacks in 2012 and was named to the SEC All-Freshman team. Spencer coached the Bowling Green defensive line in 2009-10, where he mentored Chris Jones to All-Mid-American Conference honors and helped the Falcons to the 2009 Humanitarian Bowl, despite not returning a single starter on the defensive line. Jones emerged as a starter for the New England Patriots in 2013, recording six sacks, and played the second-highest number of snaps among NFL rookie defensive tackles. From Hartford, Conn., Spencer has had two stints at Massachusetts, coaching the defensive line in 2007-08 and in 2001-03, also coordinating the special teams during his second stint with the Minutemen. He also has coached at Hofstra (2006), Villanova (2005), Holy Cross (2004), where he worked with Ricky Rahne, Trinity College (1998-2000) and Shippensburg (1996-97). A three-year starter at safety at Clarion (Pa.) University, Spencer earned his bachelor's degree in political science.
