Honestly- I think the single best thing that Ultimate tennis does is that they level people very well. You get a good match every week because it is tough to move up a level and you really have to be at the next level to do so. (At least in Atlanta where there are a lot of people at every half-level.
I like that they require extenuating circumstances to bump someone who didn't win in their league. This OP has a perfect example of someone that I don't think they should bump. Earn you way up- the league is better for it. Too many people have grossly overrated themselves and the ultimate tennis methodology does a good job of separating people within a couple seasons in my experience. For me the only people I really see who are out of level are the self rates.
