Offensive coaches aren't committed. Doug Marrone, in particular, mailed it in.

They thought they could serve a year here and get a sweet gig like Sarc.

No commitment to the players or the program.

I think Saban is fatigued from breaking in new staff. I remember a Saban quote from early this year. O'Brien recommended Marrone to Coach Saban and Saban's response was "Do you think he would take it?"

Seemed odd to me at the time.

I think Saban was frustrated by constant staff turnover and jumped at a ready made solution. He though all those years of experience would translate on the field.

The problem is, a coach must have his heart in it or his lack of commitment infects the players.

Saban is tired. There may be more to the story. It may just be being 70 post major surgery
This combined with historical success and the grind of constant turnover has taken a toll.

Is he done? No. Not necessarily. But he needs to retool with a younger, more committed staff.

Mercenaries with O'Brien and Marrone will suck the blood out of this program. Sarc and Lane had reputational issues that forced them to take a longer view. These two dudes are here for the wrong reasons.
