Yes I know they were official in '60. That was tongue-in-cheek expression......57 born in '50. As a 8 and 9 year old kid I was around north Texas when they(my dad and all his buddies) were talking about a team to rival the Texans. I remember my elementary school having contest to name the new team. One of the possible names, and I think I'm right in that it came out in the paper was the Dallas Rangers but I think they changed it to the Cowboys. There were other names floating around but I don't remember them. The Texans relocated to Kansas City (Chiefs) and then there wasn't any competition.
