Being an ex-player means very little to me. He needed more experience on the other side of the current, working on a coaching staff. He did not put in the work that a Leslie Frazer did for example, 20 yrs worth. Coaches are known for having long long hours, and most of the time the ones who work the longest hours are the assistant coaches down on the totem pole. During those early years, coaches learn and develop a work ethic and successful study habits to better prepare their teams. Those years can be tough learning experience through trial/error to develop your coaching identity but nearly every head coach in the NFL has to go through those years in order to reach the pinnacle position of Head Football Coach. Jason never went through those nitty gritty years like most current head coaches in the NFL did. His quick rise up the ladder was aided by his buddy buddy relationship with Jerry Jones. His greenness gets exposed every season with his sideline issues, once again that comes from a lack of experience from him skipping those nitty gritty years. So, the comment BB made does not surprise me one bit.
