Aikman didn't dislike Switzer, he agreed to change his offensive philosophy from the wishbone style to accommodate Aikman but he broke his leg and Switzer reverted to his old offense and Aikman transferred and almost to Miami when Switzer tried to help him get on Jimmy Johnson's team. All three men have verified this.
What Aikman didn't like about Switzer was his lack of discipline and he said coming in he was going to treat grown men like grown men. Hell, he had been loose at OU with the Wild Bunch, what did they think he was going to do coming out of retirement only because his friend asked him to?
