evidence: As if there were any doubt that the NFL was going to continue its blacklist against Colin Kaepernick, the former Super Bowl starting quarterback was once again denied an opportunity this week. This time, it was in Seattle, and there was none of the hemming and hawing about Kaepernick’s numbers not being good enough or his playstyle not being the right fit for the offense. No, instead, an NFL source told ESPN’s Adam Schefter that Seahawks officials cancelled Kaepernick’s workout after he refused to commit to ending his kneeling protests during the national anthem during the 2018 season. (Sure enough, on Friday, the Seahawks went ahead and found someone else for the job.) [...] The truth, though, is that the owners are not making business decisions when they refuse the services of men like Kaepernick and Reid. As Van Natta and Wickersham reported, the NFL’s major sponsors were not universally pro ban. In fact, at least one had threatened to drop its sponsorship of the league should it mandate the players to stand for the national anthem. If it was really about the bottom line, would the NFL have tried to buy out kneeling players for $100m in charitable contributions in 2017?
