Brandon Jackson has 108 rush attempts, 460 rush yards, 25 receptions, 193 receiving yards, and 4 total touchdowns.
Whereas Roddy White has 1 rush for 3 yards, 70 receptions for 934 yards and 7 tds.
This is a perfet example of what I was explaining earlier; running backs do it all, receivers only receive. Therefore running backs are more valuable. And that's not just because they earn extra points every time they touch the ball, receptions are worth just as much as rush attempts, but since running backs touch the ball more, they're worth more. They aren't equal in terms of production, therefore they won't be equal in terms of points.
