The Bills must not have known what they had in 28-year old running back Fred Jackson until this season.  Yesterday he became the first NFL player ever to rush for over 1,000 yards and have over 1,000 yards in kickoff returns.  Jackson finished with the 4th most all-purpose yards in a NFL season with 2,516 yards.  Jackson played in all 16 games for the Bills this season and he carried the ball 237 times for 1,062 yards (4.5 ypc) with 2 TD runs and he also caught 46 passes for 371 yards (8.1 avg) with 2 TD grabs.  On special teams, Jackson returned 41 kickoffs for 1,014 yards (24.7 avg) and he also returned 6 punts for 69 yards (11.5 avg).  Jackson touched the ball a total of 329 times this season for 2,516 yards (7.6 yards per touch) and he had 4 total TDs.  He averaged 157.3 all purpose yards per game for the Bills this season.  With Jackson likely being the main man in the running game in 2010 for the Bills he will likely give up his kick return gig.
