I was curious about my rushing theory so I looked up the numbers during the 07 post-season run. I think they bear out that while the Giants had a balanced attack, they didn't rush the ball well. I consider 4 yards per carry the standard you want to meet, 5 would be phenomenal.
Tampa Bay - Bradshaw (17-66), Jacobs (13-34) = 30 carries for 100 yards, 3.3 average
Dallas - Jacobs (14-54), Bradshaw (6-34) = 20 carries for 88 yards, 4.4 average
Green Bay - Jacobs (21-67), Bradshaw (16-63) = 37 carries for 130 yards, 3.5 average
New England - Bradshaw (9-45), Jacobs (14-42) = 23 carries for 87 yards, 3.7 average
