2. Kansas City Chiefs
In last year's rankings, we predicted big things for Kansas City based on an impressive assembly of young talent. After a division title in 2010, there's no reason to temper our expectations. The defensive back quartet of Eric Berry, Brandon Flowers, Brandon Carr and Javier Arenas represents one of the best combinations of youth and talent since the 49ers' secondary of the early 1980s. On offense, Dwayne Bowe may no longer qualify for our list, but Tony Moeaki and Dexter McCluster combine to adequately take his place.
However, the cornerstone of Kansas City's resurgence is Jamaal Charles, who enters 2011 at only 24 years of age. Last season, Charles' 6.38 yards per carry was a single-season record among qualifying running backs since the merger. The law of averages suggests that his average is likely to come down to earth going forward, but the fact it was achieved over 230 carries means Charles was by no means a one-year wonder.
