Whether it be because of injury, suspension or a new player being added to the team, you cannot just look at last season's rankings and expect a player to duplicate the same performance the following season.
Each season, the Maniaxs identify a list of 10 players that are not going to be desirable fantasy players a year after finishing high in the rankings. All 2009 fantasy rankings for this article are from profootballreference.com
1) RB Thomas Jones (Kansas City Chiefs) - He rushed for 1,402 yards and scored 14 rushing touchdowns in 2009, which put him sixth among running backs and 11th among all fantasy players. That was with the New York Jets, and when they saw Shonn Greene dominate the 2009 postseason with 54 rushes for 304 yards and two rushing touchdowns, they released Jones, and he signed with the Kansas City Chiefs.
The Chiefs already have a young emerging star in RB Jamaal Charles, who had 1,120 yards rushing and seven rushing touchdowns in 2009. They also added Mississippi RB Dexter McCluster in the second round, who should see a lot of time in the slot and in the backfield on third down. I just cannot see Jones duplicating his 2009 season, unless Charles goes down with an injury. He will probably finish in the high 30s to low 40s among fantasy running backs and is a late round choice as a fourth or fifth running back or handcuff to Charles...
