I remember when they left one of the reasons was they didn't like the offense and wanted a more open style. Bill literally tells them to shoot before they turn it over and they can jack up 3s at any time from anywhere. That reasoning doesn't make sense. I also heard that not everyone on the team was happy to see Ashley come back last year.
I believe that "style of play" is the most diplomatic answer you can give when asked about why you transferred. I'm guessing it very rarely comes down to "style of play". It's just the easiest out when questioned.
