The left side of the Jaguars' offensive line is a puzzle. Will the pieces fit together in 2016?
Four -- the number of offensive line combinations employed by the Jacksonville Jaguars last season. Four is a small number. In fact, according to Pro Football Focus, it's the second-fewest in the league in 2015.
Three -- the number of looming personnel changes within the Jaguars offensive line this season. Three is even smaller than four. Yet somehow, in this situation, three seems a lot larger in significance. While the Jaguars' offensive line was somewhat stable in 2015, the unit still didn't perform at the level it should have.
