Good Answer. (in response to my earlier question about when was the last time a rookie QB lite the world on fire). I forgot about big BEN.
However in comparison to my belief that it is much more likely for a rookie RB to lite the world on fire (than a rookie QB). check this out...
Every year has at least one (if not more) rookie RB's make immediate impact (>1000 yards).
Yr / RB name / team / yards / av YPC / TD's
2007 Adrian Pedersen Vikings 1,341 5.6 12
2007 Marshawn Lynch Buffalo 1,115 4.0 7
2006 Joseph Addai Colts 1081 4.8 19
2005 'Cadillac' Williams Tampa 1178 4.1 6
My data for 2005 & 2006 might be incomplete for rookie rushers over 1,000 yards.

1994 Marshall Faulk Indianapolis 1,282 4.1 11
1994 Errict Rhett Tampa Bay 1,011 3.6 7
Just want to say that I think if the Jets were to move up - I see it much more likely to take McFadden rather than Ryan as they are in a win NOW mode (free agency $$ acquisitions of veterans and to take heat off Mangini or else he could be out of a job)
