I agree with that probably being the strategy that a team might employ to get the most out of King, but man I would't want a guy like that on the team. Reminds me of "In case of emergency, break glass." Also, as you said, if that is the case, he isn't worth much. Carrying him on the roster, trying to decide what "big games" you have him ready for, when he practices, etc. and still not knowing if he will make it through a whole game. Reminds me a bit of former Packer CB Sam Shields after all of his concussions.
