IMO, Butch inherently trusts his/his staff's/Bob Welton's talent evals. He also may feel a bit weary of playing the games required to land certain 5* guys (Higgins rumors would lend some credence to that). Finally, he may be the type of coach who doesn't want to manage egos once guys sign their LOIs and then freak out because they aren't starting day one and start causing trouble/threatening to walk.
That philosophy doesn't preclude going after high 4* and 5* guys at as many positions as possible, but I think he's being truthful when he says that he wants high character guys. Of course, at certain positions you have to take the risk and grab the most talented player possible, but at developmental positions, you can afford to take the guys with fewer offers but a very high upside.
