Talk:Third quarterback rule

I think there was a version of this rule before 1991, but can't find any evidence online. In particular, my memory is that it played a part in some games in the 1970s, in particular the memorable Thanksgiving day game in 1974, when Clint Longley ("Mad Bomber") led the Cowboys to a win over the Washington Redskins. Does anybody else remember this? [marzolian] 208.185.201.194 (talk) 17:45, 26 September 2011 (UTC)
