I see your point but GROB kept making changes and that didn't work either, 3 coordinators in 5 years, pistol, etc etc. You also have to remember that recruiting is also a big part of the game here. If you bring in new coaches, they damn well better be able to hit the ground running, recruiting. If he gets rid of Hackett, sure people feel better from February-September but at the end of the day, the system is Marrone's and it ain't changing a ton so he will either improve on it or bust, sure he will look at tweaking it but as I have said, the job, the program and his future are on his shoulders and I am sure if he thought a new offensive system was the answer or a few new assistants on offense were the answer then he would do that.
I run my own business and there isn't a day that goes by that if I felt there was a way I could improve it that I wouldn't take the steps to do so. I think people think that Marrone is sitting around nieve to the issues, and I don't think that is the case at all. Look, I certainly am not the guys biggest cheerleader far far from it, I have made that pretty clear but I think his cards are on the table and he isnt't changing much, the foundation for what he wants to do has been in place for 3 years, the next 2 will either prove him right or wrong.
