The difference between GAA games Pre/Post 1950's(ish)

While looking back over the roll of honour in both the hurling and football championships i noticed something quite strange with the score lines, as many other may have noticed too.

The games were generally low scoring affairs with score lines of 2-1 1-3(1912 hurling final), 0-5 0-4(1918 football final), the amount of goals/points scored would be roughly the same unlike today where out of 18 scores usually 16/17 would be points.

The score lines from the finals seems to gradually increase from the early years up until the 1950's(but only slightly), for some reason though a bigger shift comes along here and score lines resemble anything you could expect in a modern game

Does anyone (with a bit more life experience, im only 22 so can't remember too far back) have any opinions why this happened?.... what changed the game and evolved it into what we see today(where teams might score 1-16 2-12 in any given game)

Maybe in the pre-1950's, they spent most to of their time on the pitch beating the crap outta one another...
It's a bit more wussy today...concentrate too much on the sliotar rather than taking out the player.

I'm only taking wild guesses here!

Down changed it from the early 60's on. They brought more hand passing into it and tried to bypass midfield as Mick O'Connell was there.

Man to man marking became less important.

I know the old soccer balls could break your feet they were so hard. Gaelic footballs were always heavier, they probably could only score points inside 20 yards where as now you can score further out the pitch.
