Mike Tanier of Sports on Earth (previously Football Outsiders and the New York Times) is one of the most insightful and humorous NFL writers. He shares his thoughts on Chris Kluwe's career. Here are some good quotes, but I encourage you to read the whole article.
There are apparently some old-timey types who consider Kluwe a potential distraction, who think he should lay off the video games and shut up about hot-button issues. If talking about the things he cherishes and believes in makes a player a distraction, then I want to be more distracted.
Smart teams do not draft punters, though smart teams do sometimes replace veteran punters to make way for a salary cap bypass.
I refuse to believe that he has tweeted his way out of the NFL by daring to take a stand. If he has, if the NFL wants to move in the direction of less personality and less courage, it’s their loss.
