He said it right out. Jerry is right there everyday. What he is saying is that he undercuts his coaches authority. Jerry looms around as the boss of bosses changing the dynamics. This is why he mentioned that in a year in Baltimore he saw owner Steve biscotti one time and that newsome and harbaugh were allowed to do their jobs. in a nutshell, Jerry robs the coaches of authority and needs to back off. Also the job of general manger is so difficult and detailed the owner can not also be the general manager. Said newsome was always working. This is why parcells removed Jerry from the practice field early on.
