Butler headed to Houston

Blue White Illustrated has confirmed with a source Monday afternoon that Penn State defensive coordinator John Butler will join former Nittany Lion head coach Bill O'Brien with the Houston Texans.
Butler, just wrapping his second season as an assistant with O'Brien, grew from a late hire on the staff, managing the Nittany Lions' secondary in 2012, to a promotion as Penn State's defensive coordinator for the 2013 season following the departure of Ted Roof to Georgia Tech last year.
Owning a lightning rod personality and developing a reputation for his fiery antics coaching Penn State's defense from the sidelines for the past two seasons, Butler finishes his one season in charge of the Lions' defense with mixed results.
Positively, the Nittany Lions were able to finish with the country's No. 36-ranked rushing defense, checking in at 144.0 yards per game given up on the ground and the No. 48-ranked overall defense, surrendering 381.3 total yards per game.
Passing yards allowed was another story though, as the Nittany Lions checked in with the No. 73-ranked passing defense, and No. 50 in team passing efficiency defense.
Butler joins Charles London, Stan Hixon, Anthony Midget and Craig Fitzgerald, all of whom submitted their letters of resignation on Monday morning.
Blue White Illustrated will continue to follow this story as it develops.
