Saban has never fired a coordinator that I am aware of. The time to start is RIGHT NOW. Both coordinators are horrible, especially O'Brien. If Bama had Kirby as DC and Kiffin as OC we would not have lost a game for over 2 years, PERIOD. I have no idea why Saban decided to go for the two point conversion twice this past Saturday but if he had kicked just one of those extra points instead Bama would have won 25-24 in regulation. Stupid decision that is on no one other than Saban.
As for playing defense, our secondary play very carelessly and recklessly. They are horrible in man coverage and have to resort to PI to keep from giving up big yards but still give up the 15 yard penalties, i.e. big yards. Saban used to be very hands-on with those guys. Not sure if that is still the case or not but it certainly doesn't seem like he does as much for the last few years. Also the entire team doesn't seem to have very much intensity. Saban needs to also fire his intinsity coach and hire someone that can get the job done...
