I am struggling to explain it adequately I know.......
Not really, but you are trying to explain how great sports are to a sports fan. You are preaching to the choir, I get that it can be an exciting game, and people love it. Some people like golf, or Tennis, or watching people drive cars really fast, or cricket or soccer, or whatever.
For the most part in many circumstances draws are really booring to watch. Yeah there may be some good ones, for instance if your team is in the world cup and you are playing the best team in the world and to get to the next round you need to not lose to them, then a draw against them would be great (not as great as an upset), but I think I can understand.
The Ashes as I understand it is a different circumstance, because it is only two teams, and the same two teams play each other for the same trophy every year, here a draw would probably result in the last winner retaining the trophy. It seems more like a rivalry game than a championship. There are a lot of these in USA college football, where one school plays another school every year (and has for 100 years) for a trophy that the winner gets to keep until next year when they both play again.
