You don’t need to know Saban personally, his rants are easy to find. He’s a screamer. He’s smart enough to realize that in this modern world you can’t scream at the players anymore, so he screams at the coaches. He’s a walking temper tantrum on the sideline, any missed play, no matter how much they’re winning by, can set him off. And apparently he’s much worse in practice. He’s a jerk and a bully, the footage is all over youtube.
And Dabo might be sneaking up on him both in this game and maybe even for his job.
