Rewrite that above sentence with any past or present Cowboy QB, coach, player or owner and it has at one time or the other been proclaimed loud enough to wake the dead in Outer Mongolia or in the ancient sands of Mars!
Hell, even Captain America, the immortal Roger Staubach had his media boo-birds and naysayers! "He only won half of his Super Bowls" or such crap.
Dallas is a bitcher’s town. Always has been and always will be. That is the only downside to being a True-Blue Cowboy's fan. I want them to win a Super Bowl ever year, but when they don't, I figure next year we will.
The Dallas Cowboys have been in 8 of the 42 Super Bowls that have ever been played (That's nearly 20% of those played!) and won 5. No other team has been there more nor won more, so even with all the so-called baggage, I'll take being a Dallas Cowboys fan over any other team.

drop dead, follow him-to-hell-handsome is a also a plus I enjoy!
