I abandoned Dallas when Jerry Jones fired Jimmy Johnson.
*To clarify, that was the beginning of the end for me. I stuck with the team for a few years, but after the core of the Super Bowl teams retired and Romo became the permanent starter, I gave up and won't be a Cowboys fan again until Jerry Jones sells the team or dies. Can't support, "Th-Uh Texans" so I'm basically a free agent during football season, when the Oilers left Houston, I was done with football from H-Town and after the Astros cheating scandal, I'm done with baseball from Houston, too. I support all three NBA teams from Texas, but my two teams now are The Spurs in the NBA and The Rangers in MLB. I was a "whoever is playing the Patriots fan", but since Brady left, I don't know, I still hate Belichick.
