"In his first season in Arizona, Bettcher helped coach a Cardinals defense that collected 47 sacks, the third-highest total in franchise history, while also finishing with the NFL’s sixth-ranked overall defense and featuring the league’s top-ranked run defense (84.4 yards per game). The Cardinals allowed the fewest rushing yards in team history for a 16-game season (1,351). OLB John Abraham was selected to his fifth career Pro Bowl, and first as a linebacker, after he led the team with 11.5 sacks in 2013, the most sacks by a linebacker in a single-season in team history.
In 2012, Bettcher assisted Colts head coach Chuck Pagano and 2012 NFL Coach of the Year Bruce Arians, who served as interim coach for 12 games while Pagano was receiving treatment for leukemia. Bettcher coached the Colts outside linebackers, helping Robert Mathis earn a selection to his first Pro Bowl at OLB and fifth selection overall. The Colts improved from 2-14 in 2011 to 11-5 in 2012, tied for the third-largest turnaround in NFL history and earned a Wild Card berth in the AFC playoffs.
Prior to joining the Colts, Bettcher spent nine years in the college coaching ranks. In 2011, he served as linebackers coach/special teams coordinator at New Hampshire, and he coached the NCAA FCS leading tackler and 2011 Buck Buchanan Award Winner (FCS National Defensive Player of the Year), Matt Evans. He also helped the Wildcats rank in the top 20 nationally in both punt return and punt coverage.
Bettcher coached defensive ends and special teams at Ball State in 2010, where he helped tutor Robert Eddins who led the team in sacks and earned All-MAC honors. From 2007-2009, Bettcher worked as a defensive assistant/defensive graduate assistant at the University of North Carolina, coaching linebackers and special teams and helped the 2009 team finish sixth in the nation in overall defense. At UNC, Bettcher worked with future NFL Pro Bowler Robert Quinn in addition to linebackers Bruce Carter and Quinton Coples. In 2006, he was a defensive graduate assistant at Bowling Green State University, working with the secondary and special teams units."
Once again I think it's an excellent decision.
