 With extensive knowledge regarding the intricacies of the defense , Ryan has been criticized for not devoting similar time and effort into coaching the offense . Ryan refuted this , stating his goal is to implement a proficient running game , citing a desire to " get after " the opponent through running the ball . Ryan has also stated that passing the ball is important but should not be used incessantly as there should be a balance between both aspects of the offense . In 2009 and 2010 , the Jets were ranked first and fourth overall in the league in rushing which coincided with their two playoff appearances . In 2011 , the Jets attempted to convert to a more pass @-@ oriented offense , which have become more widely used in the NFL , however , the team struggled with this adjustment and reverted to their former run @-@ oriented offense by the middle of the season . His defensive strategy , in contrast , tends to be more elaborate taking into consideration his experience in the field . There are six different defensive formations utilized in football , but the two commonly used formations are the 3 – 4 formation , with three defensive lineman and four linebackers , and the 4 – 3 formation , with four defensive lineman and three linebackers . The Jets utilized the former of the two popular formations ; however , Ryan tended to employ all six formations in varying forms . Furthermore , he often calls audibles that have the defense line up in one formation and switch to another so as to cloak their intentions and confuse and pressure the opponent .
