Are you saying you'd prefer calling divisions U17 and U19 instead of Junior/Senior? What other sports actually do that? I can think of soccer. But other sports like gymnastics, figure skating, a lot of the Olympic sports, have Junior and Senior divisions. I haven't heard of U17 much. I think "Youth/Junior/Senior" rolls off the tongue a little better than "U 19". And given that announcers at competitions have to introduce hundreds of teams, I'm guessing they'd prefer saying Sr/Jr over numbers. It would be nice if USASF and IASF divisions were one-and-the-same at some point though. I know there are reasons why they aren't, but when you see a Jr 2 team and a U17 team and it's literally the same type of team, it's kind of funny to have them in different divisions. It's also funny to see divisions considered "International" when there are never any international competitors. Really, having so many divisions has watered down the competition here in the US, especially at small competitions where there might be only one U19 Level 2 team and one Sr Level 2 team competing.
