I will defend the Cowboy stadium name because you are technically correct. However, you did get a few wrong.
The Bills' stadium was named Rich Stadium in 1973.
The Dolphins' stadium was named Joe Robbie stadium from 1987-1996
Titans' stadium was named Adelphia Coliseum from 1999-2002, then The Coliseum from 2002-2006 - THEN it was LP Field from 2006-2015. Now it is Nissan Stadium.
