From what I've read about him, that's just who he is. He reads motivational stuff, writes down motivational ideas his has whenever he has one (even keeps a recorder/notepad on the nightstand), and is very much a cliche using kinda guy. However, I don't think he does it to fluff so much as he believes in the power of positive thinking and picks up any kind of motivational technique he can find that he thinks will motivate himself and his team.
His father was a cop and he has a very blue collar background that influenced him deeply. Cincy fans warned that after a while a lot of the phrases he uses would get annoying because he says them so much and they probably will but I think that's just who is. He's not trying to be a used car salesman, he just loves positive thinking and cliches.
It's just a part of him that we'll have to develop an immunity too. Sort of like those teachers who say certain words a funny way or use certain phrases a lot that we all had to get used to in class (or if you were like me as kid, you learned to imitate their speech and wrote down how many times they said it just to have a little fun in class).
In time, I foresee VolNation having threads on Butchisms that will be pretty funny and hopefully we'll be winning so they'll be in good fun rather than mean-spirited.
But hey we all have our quirks that other people see a lot better than we do.
