Harbaugh would have been fine. He's had success at the NFL level so he had that going for him. Still would have preferred Bieniemy (or Leftwich or Ryans or Morris) over him but I think the Vikings would have done better initially with Harbaugh at the helm than O'Connell. Who knows? Maybe O'Connell is the next boy genius head coach and the Vikings will have long term success. One can only hope.
