Apparently there is great dissatisfaction with Cassel and the Chiefs have been known to do stuff like this in the past. Here is the article; http://arrowheadaddict.com/2012/01/04/the-chiefs-may-be-fishing-for-a-new-qb/
Thanks for the link, that's pretty interesting.
If I was a GM or owner of a team, I'd go after a coach or offensive coordinator that can develop a quarterback. Most particularly, I'd want someone that could do it like the guys in Carolina with Cam Newton. The last kind of offensive mind I would want is John Fox in Denver, (even though most of that isn't really his fault, he knows his quarterback can't complete passes.)
