Johnson's success was between the tackles

Chris Johnson's big day in Houston was certainly a major sign of progress. The Titans run game had done nothing to show it could produce. Then, against a strong defensive front, the offensive line paved the way for a 141-yard rushing day.

Even if those numbers were padded with some late yards against backups, the day’s efforts were meaningful.

At his best, Johnson made a living gaining the edge and turning the corner.

What does it say that, per ESPN Stats & Info, only one of Johnson’s yards Sunday came outside?

The rest came inside the tackles.

At Reliant Stadium, Johnson averaged a season-high 4.65 yards before contact per rush inside the tackles, and was hit in the backfield only once on 25 rushes.

Before that, Johnson was averaging 1.3 yards before contact per rush and was contacted in the backfield on seven of his 27 rush attempts inside the tackles entering Sunday.

There is good stuff for the line to look at regarding the run.
