It sounds like he chose to leave Wisconsin. I found this excerpt on their SB Nation site from an article about him departing for Vandy:
At Wisconsin, Breckterfield has been a mainstay on the defensive staff and recruiting trail for the Badgers. He has helped mold the defensive line into one of the top, albeit unheralded, units in the Big Ten. The Badgers have allowed an average of just 16.5 points per game since Breckterfield joined the coaching staff, ranking No. 3 nationally over those five years. UW ranks No. 3 in yards allowed during that span, as well, giving up just 292.3 total yards per contest, and stands third in both rushing defense (109.0 ypg) and pass efficiency defense (106.6) over the course of those seasons. This year the defense was just as good, only giving up 96.1 rushing yards per game.[/i]
They called Wisconsin "UW". Not me. Don't twist.
