Now that the Jacksonville Jaguars regular season is nearly finished, and the door to the playoffs has shut for good, it's becoming much easier to look back at the 2015 season to see what went right and what went wrong.
The answer to that is pretty obvious for the Jaguars, especially on the defensive side. Essentially, the only group that performed up to expectations and, honestly, above those expectations were the linebackers, but the defensive front and secondary were major liabilities on the other hand.
Which probably was the worst possible situation for the Jaguars defense.
