I've long thought it would be interesting to score brackets so that you get a points according to the seed of your team, for each game they win.
If, say, you pick a 12 seed to win in the first round. If they win in the second round: 12 points. I think that would be fun. It mixes things up a lot. People argue that you'd just pick all the higher seeds. I asked AI, and it said that would be a bad strategy. So, you would have to use some discernment. A lot more discernment than in the traditional scoring methods.
