Timid RBs getting stopped behind the line don't generally average 5 yards.
he has averaged more negative yards per carry the last 2 seasons vs 2007.
Sure they do if they run for a 50 yard play around the end and then get stuffed for 3 plays behind the line and then average 3 yards per carry for the next 10 plays. Lets say the negative plays were for minus 3 yards a piece. So we have 14 plays for a total of 71 or a total of 5 yards per play.
As for the comparison to the past 2 years do you have stats to show that or did you make it up??
