The "a raise with a better boss" talking point is hilarious. He would have been paid the same at KSU if that's all he wanted. So now we're just left with "I picked up and moved because I don't like the boss I talk to once a week at most" reasoning, which is so utterly ridiculous. If Currie is that evil, there would be a lot more stories leaking out of that department.
I don't know why he left, but if you think it's because his boss ran him off, directly or indirectly, you're tremendously gullible, or simply in denial.
