For those of you who are new to this, the Running Back Success Rate is a measure of how "successful" each of a running back's rushing attempts are. A "successful" run is one that :
Gains at least 40% of the yardage needed to move the chains on 1st down
Gains at least 60% of the yardage needed to move the chains on 2nd down
Gains at least 100% of the yardage needed to move the chains on 3rd and 4th down
On to the numbers...
WEEK TEN
| Player | Team | Total ATT | Successful ATT | Success Rate | Gained | AVG |
| Trent Richardson | Alabama | 23 | 9 | 39% | 89 | 3.9 |
| Eddie Lacy | Alabama | 5 | 1 | 20% | 19 | 3.8 |
| Ronnie Wingo | Arkansas | 2 | 2 | 100% | 9 | 4.5 |
| Jeff Demps | Florida | 23 | 14 | 61% | 158 | 6.9 |
| Spencer Ware | LSU | 16 | 5 | 31% | 29 | 1.8 |
| Michael Ford | LSU | 11 | 9 | 82% | 72 | 6.5 |
| Vick Ballard | Mississippi State | 11 | 8 | 73% | 102 | 9.3 |
| Tauren Poole | Tennessee | 11 | 3 | 27% | 13 | 1.2 |
After crunching the numbers on Trent Richardson, Eddie Lacy, and Spencer Ware and seeing that they all came in with very below average numbers I was getting ready to talk about the amazing performance by both the Alabama and LSU defenses...and then I started looking at Michael Ford. With 9 of 11 runs being successful (two of which went for 10+ yards), he posted a week's best 82% (if you ignore Ronnie Wingo's two carry, nine yard, 100% performance, which I am). Asterik alert, he was the beneficiary of several speed option pitches that gave him a little bit of an unfair boost over the rest of the backs, but credit where it's due, Ford put up good numbers against a great defense so hat's off to him.
The two other great performances this week belong to Mississippi State's Vick Ballard, who took advantage of the FCS defense of UT-Martin to put up big numbers, and Jeff Demps, who seems to have gotten back on track with a very good 61% success rate and 6.9 ypc average.

| Tauren Poole | Tennessee | 9 | 145 | 59 | 41% | 513 | 3.5 |
From the cumulative view, nothing really changed from last week as all the category leaders essentially remained the same (though Michael Dyer and Marcus Lattimore, who were tied in total yards and # of successful attempts, respectively, with Trent Richardson were surpassed as both did not play) despite an averaging downward by pretty much everyone. Vick Ballard and Michael Ford averaged up in most of their categories thanks to good weeks, but for the most part I think we're really seeing a leveling off here. Honestly, can't wait 'til the end of the season (well, I CAN wait, please don't ever end football season, please please please) to actually chart all these on a week by week basis to see how they evolved over the course of a whole year.
