Combined with hiring of Terry Joseph, an absolutely terrible evaluator, this is shittastic news. Joseph's hire was fucking terrible on several levels but I was heartened a little by the fact that Chang and his staff would be in place to help ensure that Joseph couldn't fill the DB room with spares.
Every single coach from the Saban tree has said this exact thing. The only one that has done well (Kirby) has done it - not by replicating the entire Bama model - but instead by dropping bags in egregious fashion. Also important, you can remake the personnel department to be more like Bama while also retaining guys that are very good at their jobs and folding them into the department. Maybe Sark will be the first to accomplish the replication but I'm not going to hold my breath.
Rhule has an athletic profile for each spot and he tries to stick within the boundary of that profile and then develop them with teachers on staff. It's built on the backbone of the way that Bowden and Jimmy Johnson often ignored rankings and known players for guys that fit a specific athletic profile. It's how you avoid signing Brian Williams or RJ Henderson, etc ... There's no special sauce other than identifying athletes, the Rhule special sauce is in developing them. Chang and his team have done a good job finding those type of athletic traits - their development has been a mixed bag.
