This is something I did a few times last season and plan on doing for every game this season.

Explanation:

Each individual rush is considered on it's own, and measured by it's "success." A run is considered successful if it gets 40% of the yardage needed to move the chains on first down, 60% of the yardage needed on second down, and 100% of the yardage needed on third or fourth down. This is a much more accurate overall picture of how well a running back does in a game than just the total yardage or ypc averages because it ignores big run outliers that can skew those kinds of stats

Using these metrics, the Titans were successful on 26% of their runs last night.  It would have been nice to see them get a few more attempts in there.

Here's a question:   Frank Wycheck said on the radio this morning that the 32-yard cutback run by CJ was a designed cutback play.  Why didn't the Titans try to run that play again at some point later in the game?
