It's tough to assess just how great a manager he was, I'll definitely grant you that. He took over from Carly Fiorina at HP, and she wasn't exactly a tough act to follow (although her predecessors obviously were.) As long as he didn't set the building on fire, he was going to come out looking good after her tenure.

And certainly, nobody who worked at Oracle will be remembered as one of the all-time best-loved business figures.
