Now granted I turned 12 back in September of 1978, but when the Rams were moving on from Knox, I wanted Bill Walsh because of his offense and felt the Rams needed an offensive type Head Coach.
They interviewed several including Walsh, Don Coryell & Dan Reeves of the Cowboys, but in the end Rosenbloom went with Allen because of his regular season record. Both GM Don Klosterman & Carroll's son Steve Rosenbloom were against the Allen hiring and campaigned for Dan Reeves because Reeves would bring in the Cowboy offense, but in the end Carroll sited the fact that Allen won games, albeit his post season record at that time was worse then Knox, who was fired because of his lack of post season success.
After that decision and then firing George Allen after only two preseason games, Rosenbloom shared with his wife Georgia, his biggest mistake was letting Chuck Knox go and thus is the reason that Georgia brought back Knox in 1992, when John Shaw had recommended hiring Mike Holmgren.
