This implies that the turnover was planned. Outside of the OL coach, the movement was coming from the coaches moving on to advance their careers (getting a promotion). One could argue that one of coaches ended up as a defensive coordinator and we could have offered him our DC position. Note that he only became a DC with GB after already moving across the stadium to the chargers. Nonetheless, another team thought highly enough of him to give him a coordinator position. The rams instead went with more of a veteran coach, Morris, instead of the new blood there. That sort of goes against some of the points in the article.
