Peter King mentioned in his "10 things I think" or whatever, that he "thought he was hearing" that VY was rebuffing KC as mentor.
However,
a) who knows if that's even true
b) who knows what history exists between KC and VY
c) what qualifies KC as a mentor? just because he has the experience, doesn't mean he's able to relate well to a young qb...or maybe KC's just still a prick...or maybe any number of things.
Chris Simms may be just as well qualified to mentor VY, and VY seems to relate well to him and get along very well with him.
Of course, the Titans blew their best opportunity to mentor VY when they locked (VY's Godfather) Steve McNair out of the facility.
