Mariucci didn't coach the 49ers last year. If you want to point the finger why he left the team, you need to go to the owners, the DeBartolo sister and her idiot husband who has dismantled the team with their tightwad pay.
Don't get me started, her brother should have never got involved with that scheme, what was it in St. Louis?
Her husband is a first class idiot.
Free Eddie DeBartolo!! OK, so he's not in jail but he doesn't control the team anymore.
