Yeah framing it as collusion rather than just discriminatory employment practices is quite a strange one, though the latter might be even more “unprovable” unless they get hold of a GM-Owner conversation recorded on tape
I know this won’t prove it in a court of law but surely there are less than 5 teams (or perhaps all but one team?) where Kaepernick wouldn’t be better than their backup or third place qb? I know in some cases the stability of a rookie they’ve had for a couple of years may appeal but surely someone like the Colts or Packers could make use of him as a stopgap?
