The fundamental reason CK is not signed as a starting quarterback,as he believes he should be, is because he is a one dimensional player whose only skill is the read option offense that defenses have caught up with. When forced to stay in the pocket he takes too long to go through his progressions and get the ball away with his long delivery motion resulting in sacks, hurries, blocked or tipped passes and scrambling runs. If he were a good quarterback all of his SJW routine would be swept under the carpet and ignored.
He's not willing to play for what teams are willing to pay him.
He overvalues his skills, which would make just about anybody in any profession unemployed.
His lack of a job gets a lot of press because it serves the agenda of others, but it really comes down to economics.
He often locks on to his primary receiver and doesn’t even go through his progressions before he decides to take off. The D can cheat on their coverage when they know where he is going to throw, and when he takes off, he has a spy waiting for him.
