The Kansas City Chiefs began working on overhauling their wide receiver corps by releasing Donnie Avery and A.J. Jenkins.

Jenkins, the 49ers' No. 30 overall pick in 2012, is one of the biggest draft busts in recent memory. He has managed a paltry 17 receptions for 223 yards in three NFL seasons under Jim Harbaugh and Andy Reid, two of the most respected offensive coaches in the game.

The Chiefs became the first tteam since the 1970 merger to not have a single touchdown scored by a wide receiver.
