Well if Janie McCauley characterized him as rah-rah, it MUST be true!
Look, I was getting interested in Harbaugh as a potential Rams Head Coach back when he was actually making people start to talk about the University of San Diego football program of all things. I've followed him through his time at Stanford and, of course unfortunately the 49ers. I have never once thought of him as a rah-rah type, but that is of course the kind of box I suppose he has to be put in simply because he is visibly intense. Whatever.
In any case, that article explains exactly how he's not anything like Gregg Williams.
And yes, he's proven at every level, at every step of the way, he knows how to build a program and win frequently and consistently. There is no surer thing out there. Kroenke should do whatever it takes, and then some, to get him.
