One of the familiar talking points of the never-ending offseason Colin Kaepernick-unemployment drama goes like this: Teams aren't blackballing him because of his political activism. They just don't want the "media circus" and distractions that come from signing him. If he were Tom Brady, it would be different. But as a backup or reclamation project, he's just not worth the headache.
An interesting theory. Except here's the thing: The circus rolls through fast.
If a team had signed Kaepernick, whether in March or last week, that circus would already have folded its tents.
