Baseball lost me at their first 'players strike' way back when.
Ditto on football - and had already quit rooting for most teams due to the increasing criminal behaviour of so many of its players.
Tom Landry was the Last GREAT Coach of the teams I watched, a strong Christian Man who always gave an appropriate witness. He did not put up with immoral and criminal players. He fired them.
Cowboys owner Clint Murchison Jr. and president Tex Schramm were also men with integrity. Respected all three of them.
When that famous offensive lineman, Mark Tuinei, died after retiring of heart attack by Cocaine - that was the end of the Cowboy as 'hero' for me. Yeah - been a long time.
Roger Staubach - Still, and always will be, a mensch - A Man worthy of respect.
