Way back in 2011, current Green Bay Packers’ defensive coordinator Mike Pettine was the defensive coordinator for the New York Jets under Rex Ryan. 2011 was a turbulent season for New York as, following up a near-Super Bowl run in 2010, things fell apart completely. That season is captured wonderfully by Nicholas Dawidoff in his 2013 book, “Collision Low Crossers,” in which Dawidoff was given unprecedented access to the Jets’ coaching staff and players for the entire 2011 season.
For a fan of Wisconsin sports, the book turns out to be an extremely interesting read as two of the main characters of the story are Pettine and current Wisconsin Badgers’ defensive coordinator Jim Leonhard, then a safety for the Jets.
