Former NFL quarterback Colin Kaepernick will file a grievance with the NFL players union alleging collusion among owners to keep him out of the league.

The Hill:

Kaepernick and his attorneys accuse NFL teams of displaying "unusual and bizarre behavior" during the 2017 offseason, according to the court documents originally obtained by ABC News.

"Multiple NFL head coaches and general managers stated that they wanted to sign Mr. Kaepernick, only to mysteriously go silent with no explanation and no contract offer made to Mr. Kaepernick," the complaint reads. "Other NFL teams stated they had no interest in Mr. Kaepernick and refused to explain why."

The court filings also mention President Trump's comments at a rally in Alabama last month, in which he referred to NFL players who kneel during the anthem as "sons of bitches."

Kaepernick's complaint says Trump and Vice President Mike Pence have "engaged in various public relations stunts designed to retaliate against Mr. Kaepernick and other players that have joined in Kaepernick's peaceful protest."

The complaint calls Trump "an organizing force in the collusion among team owners in their conduct towards" Kaepernick, and claims NFL owners have described Trump's administration as "causing paradigm shifts in their views toward NFL players."

The former San Francisco 49ers quarterback wasn't signed to a team in the off season after opting out of his contract with the 49ers in March, and has yet to receive a contract to play for a new team several weeks into the 2017 NFL season.

Freeman reported Kaepernick is preparing a statement on his grievance, which will come under the current collective bargaining agreement between NFL players and owners.

Colin Kaepernick is a marginal backup quarterback at best.  Even without his protest, he would have had a hard time hooking up with another NFL team.

Collusion among owners isn't necessary.  Not signing such a disruptive, toxic player is a no-brainer, and owners didn't have to conspire to realize individually the damage that would be done to their brand if Kaepernick had been on their team.  Kaepernick appears to be saying owners must be forced to ruin their businesses by hiring a wildly unpopular and disruptive player.

Some of that grievance sounds like a paranoid conspiracy theory.  Trump as "an organizing force in the collusion among team owners in their conduct"?  Really?  How did Trump "organize" the league to deny Kaepernick a job?  What phone calls or meetings took place between Trump and the owners to keep him out of the league? 

Sheesh.

Kaepernick has hit upon a novel approach to gaining employment as an unqualified worker in an industry that can't afford incompetence.  I wish him well in his next job – grocery store bagger or perhaps burger-flipper.
