Rotoworld has a complete breakdown of all free agent quarterbacks this offseason, including current Chiefs' quarterback Kyle Orton, as well as a few names that could replace him and challenge Matt Cassel in Kansas City.

Dubbing Orton a "viable gun-for-hire" but a liability especially on third downs, Rotoworld pegged his best chance for significant playing time as Jacksonville, without ruling out a return to KC:

The Chiefs reportedly maintain an interest in bringing the veteran back as competition for an underwhelming Matt Cassel. With the Kansas City brass silently cheering for Cassel to finally emerge as a franchise quarterback, however, Orton’s best chance at immediate playing time may be in Jacksonville. New coach Mike Mularkey and OC Bob Bradkowski are seeking a mentor to enable Blaine Gabbert, clearly not ready for prime time, to sit and learn for a while. From a financial point of view, Orton should have accepted the $27 million extension the Dolphins offered as part of a trade with Denver last summer.

One name that could potentially replace Orton on the roster is soon-to-be former Raiders quarterback Jason Campbell, dubbed by Rotoworld as a "solid but unspectacular" starter. Campbell is all but gone from the Raiders, who will enter 2012 with Carson Palmer as their starter, and could provide the Chiefs with another intra-divisional "bitter bridesmaid" storyline like Orton:

Campbell can’t return to Oakland because he would reportedly become a "polarizing" force among a wide receiver corps that viewed him as an offensive leader prior to the Carson Palmer trade. For the first time in a half-decade, Campbell will not go into training camp with a starting job all but locked up. His best bet may be to re-join QBs coach Jim Zorn in Kansas City as competition for Matt Cassel.
