Based on what? 113 yard against Detroit doesn’t impress me much. I think any RB that got 20 carries against Detroit could have produced the same type of numbers. Who recalls when Artose Pinner ran for 125 yards and 3 TDs against Detroit the year before?
You're wrong about Detroit. Opponents in 2007, rushes, average Y/CGB 46 6.22
PHI 28 6.00
SD 49 5.45
MIN 59 5.22
TB 23 4.96
DAL 15 4.80
OAK 20 4.45
WAS 32 3.69
KC 18 3.50
CHI 35 3.49
ARI 24 3.12
NYG 22 3.05
DEN 15 2.87
They were a below average run D last year, but closer to the average than the worst. Jackson also managed a similar Y/C late in the season on limited carries vs the Bears and Seahawks.
But my prediction has nothing to do with this. It's based on a model. It could be wrong, but it seems awfully good at slotting RBs into the right tiers and
I've got more faith in it than I do subjective opinion (mine or anyone else's).
