The departure of O'Neil (who was diplomatic), Wermers (who put his foot in his mouth) and Boren, Ciurella (sp!) has less to do with "family atmosphere" and more to do with a different focus on lineman attributes. I didn't go back to look at the rankings for Rhocko Khoury the remaining linemen relative to Wermers or O'Neill (I think O'Neill was first lineman in the state if I recall) but I suspect that they fell behind the other guys on the depth chart, and realized that were unlikely to move ahead. If so, and writing on the wall for lack of p.t., with other more mobile linemen on the way in from recruiting, why continue to get beat up? I mean they can go to OSU, or BSU, or WMU and get back on the Boren pizza and milkshake plan, gain a bunch of fat and maybe even get drafted while not having to put up with insane competition and Barwis.
I thought that myself when I read that article that talked about a Data Scientist(tm)
