One reason is this past year's team doesn't have draft numbers yet, but Greg Robinson will be a top 5 pick, Mason will be one of the first RBs off the board, and Dee Ford might be in the first round, so the numbers are about to go up. Another reason is who the players were. Cam and Nick Fairly were pretty much a two man team in 2010. I think Ziemba was drafted too, from that OL. Plus you had Michael Dyer, who isn't in the draft numbers but had a thousand plus yards in 2010.
