They have a way out.
Sign Kaepernick. Throw him out there and let him get his clock cleaned (which would ABSOLUTELY happen). Send him out with a career-ending concussion and he’ll be out of their hair for good.
As it is none of us are watching their games anyway.
Building on the above comment. Late this season, assuming it is still on, get one of the worse teams with the poorest offensive lines and the toughest remaining schedules. Get him signed, start him and let nature take its course.
