Colin Kaepernick is still going ahead with his grievance against the NFL in regards to collusion to keep him out of the league. According to CBS Sports, the NFL has given about 100,000 documents to Kaepernick's attorneys. The suit was filed midseason with Kaepernick never getting picked up by anyone throughout all of 2017. The only team he visited with was the Seahawks. The documents are part of the discovery process and include text, email and other communications between coaches, general managers and league officials.
Kaepernick last played in the NFL for the 49ers in 2016.
