As it stands IOTL, gridiron football is one of the most innovative sports. Instant replay was adopted very quickly, the coach headset was accepted early on, and most importantly, a lot of modern football equipment would be unrecognizable to a player around the turn of the last century. Compared to say, baseball or soccer, which have had innovations but most everything else has remained laregely unchanged. A baseball player from 1900 is going to know how to use a modern bat, and an association footballer would be able to recognize a modern day soccer ball fairly easily.
So, what would need to be changed culturally in order for gridiron football to be more conservative?
Some ground rules for this scenario: Relatively minor innovations such as different materials used for the jersey may be allowed. Also, the the POD must be after 1905, when TR and a bunch of coaches set standardized rules. But it must remain fairly recognizable as football, and called football by North Americans. So no cheating and just importing rugby
