Yeah, and Major League Baseball used to consist of the National League back before the flood.................Noah's flood. The "junior circuit", the American League has been around since about electricity and running water.
Lets bring up how great the 1897 Beige Sox were while discussing MLB Titles too.
Fact is, the Eagles won their paltry 3 trophys over 60 years in a league that's as different as the NACC Rugby league is to the modern NFL. This current brand and breed of NFL Football began with the merger of the NFL and AFL around 1970. The last team of the "Tin Lizzy" NFL to make it's mark were those 60's Packer teams. Even then, they were barely beyond leather helmets and no facemasks.
Rules of thumb when comparing the 1960 Eagles to the 1995 Cowboys:
If players were regularly still playing both ways, it don't count.
If the goal-post's were still on the goal line, it don't count.
If the uniforms fit like pajama's, it don't count.
If players didn't make enough money to fix their teeth, it don't count.
If you could play in a SB and star in it with a hangover, it don't count.
If the endzone had no logo's, only slanted lines, it don't count.
And, most importantly, if the Eagles could win it all, it don't count!
