The Jacksonville Jaguars took a massive step back from a pass rushing standpoint this past season, largely due to the absence of top passer Sen'Derrick Marks.
Going from Top 10 in the league to the middle of the pack was a poor year-to-year transition that was caused by several missteps in playing calling and in depth. Most notably, the team's sack leader from the previous year, Marks, played sparingly due to his season being sandwiched between two significant injuries.
Marks tore his ACL late in his breakout 2014 season and spent several months trying to will his way back into the fold, as the Jaguars struggled mightily in getting to opposing quarterbacks.
