Games are won and lost in the trenches. It's an old maxim, but a good one.
The Titans' interior line play was somewhat poorer than usual in 2010, but that looks to change. Despite returning all the same starting linemen, the Titans interior line opened up holes for Jamie Harper all day long in the preseason.
Now, with the two-headed rushing attack of Jamie Harper and Chris Johnson, the Titans will really be able to do some damage at the ground level.
The Jaguars offensive line, on the other hand, is pretty weak and will have a more difficult time opening up holes for Maurice Jones-Drew.
To make things better for the Titans, the Jaguars have a pretty weak front seven on defense. While there are great players like Tyson Alualu and recent acquisitions Paul Posluszny and Aaron Kampman, the Jaguars defensive front is improved, but nothing special.
The Titans defensive line isn't much better with Derrick Morgan injured, but the Jaguars offensive line isn't elite. Besides, ends Jason Jones and Dave Ball are still a force to be reckoned with.
The Titans have a decent defensive front and an elite offensive line, while the Jaguars defensive and offensive front are only pretty good.
The Titans win the battle of the trenches.
