The Dallas Cowboys are the greatest American football franchise since 1960.

I will be using Wikipedia as a reliable source. I will begin my case with four premises. i. The Cowboys are more valuable than any other franchise. ii. The Cowboys have the highest overall winning percentage. iii. The Cowboys retain the most fans. iv. Therefore The Cowboys are the GREATEST franchise since 1960. I will start with premise one. Easy enough, here is the link that provides a reliable resource to state the fact of premise one. http://www.forbes.com... . As you can see, the Dallas Cowboys are by far the most valuable franchise in the NFL. The closest team to come close is the Pats. The difference is a whopping $6 BILLION. They are the 5th most valuable sports franchise in the world. http://www.forbes.com... With the supporting evidence I have set forth premise one is not falsifiable. In premise two I stated that the Cowboys have obtained the highest overall winning percentage since the 1960's. Here is my source of information. http://en.wikipedia.org... http://michigan-football.com... As you can see with a percentage of .574 the Cowboys lead in the overall rating. Now I know the resources being used go back before 1960, but since the Cowboys franchise wasn't started until 1960 it benefits me none. If you were to get the average of overall wins the Cowboys division have vs the 2nd best franchise's, no matter which division you choose, the strength of the Cowboys would be stronger. What does this have to do with you ask? The Cowboys also have the most division titles with 22 (2015 season not in resource below) and most playoff berths with 31. Nine of those 31 are consecutive, which is the most. They have won 34 total postseason games which is also the most. http://www.nfl.com... (MISSING 2015 SEASON) http://en.wikipedia.org... They have the most consecutive winning seasons with 20 from 1966 to 1985. Tied with 8 Superbowl appearances, the Cowboys are with a record of 5 wins 3 losses. That's just 1 behind the current record holder to most Superbowl wins. http://en.wikipedia.org...(team) All this done in what you could call the toughest Division in the NFL. (But that's for another debate) They are one of only a few teams to have back to back Superbowl wins. Now that I have shown you that the Cowboys are the most winning-est team lets move on. Now to premise three. Short "proof" could be stated with one statement: "America's Team" Funny, huh? Let us get to the real evidence. The easiest way I felt to do this was to take the two most commonly used social medias and see which franchises were liked the most. I think we could all agree that anyone who is well, anyone, at least has a Facebook account.. http://fanpagelist.com... As you can see the Cowboys beat out the highest total likes by 1,840,209. I mean as I sit here writing this (while watching the Ottawa vs Montreal NHL game) I overhear P.K. Subban talking about the greatest sports team in the world, the Cowboys. Now there may be more polls out there that may state otherwise, I will leave that up to the Con to prove this fallacy. Greatness, at least in my opinion, comes from primarily three things: value, success in your goal "winning", and being acknowledged and accepted for achieving that goal. Not only have the Cowboys achieved these three things but history has shown they achieve it time and time again. You could also look at the Hall of Fame inductees the Cowboys have. They are tied at 16 inductees with Oakland for the top number since 1960. http://www.profootballhof.com... They have historically great players, coaches, and dynasties. When you speak to anyone about the NFL whether they know much about it or not, chances are they will know who the Cowboys are. With all of my evidence the Burden of Proof is on my opponent to prove that there is a greater franchise. If all of my premises are true than how could there be any greater franchise than the Dallas Cowboys? Thanks!
