In fairness, while firing a coach after his first year is far from the norm, it is not unprecedented. Mike Mularkey was let go by the Jacksonville Jaguars after a single 2-14 season in 2012, and the Oakland Raiders dumped Hue Jackson despite an 8-8 campaign in 2011, his first year as a head coach. The Seahawks deep-sixed Jimmy Mora following a 5-11 campaign in '09, and even Pete Carroll -- the man who replaced Mora in Seattle -- was a prior victim of a one-and-done move, losing his job after a 6-10 season with the New York Jets in 1994.
Kaepernick isn't the electric player he showed flashes of a few years ago. But he is undeniably talented, and would be at least a backup somewhere if he hadn't become the public face of a movement for refusing to stand during the national anthem. At his best, Kaepernick is undeniably better than, say, the Jacksonville Jaguars' woeful quarterback duo of Blake Bortles and Chad Henne. But Kaepernick hasn't been his best in years. He had to fight to hold off Blaine Gabbert — a quarterback so bad he was replaced by Bortles in Jacksonville — to keep his job.
