The true score theory is trying to decompose an outcome into true ability and random error. My example was about the random error (which definitely applies to sports, I'm not sure why you think it doesn't). I never ruled out the skill/ability. It's interesting that you are objecting to my argument by referring to the true score theory, which quite literally provides a caveat to attributing skills to the observed outcomes. > you imply (incorrectly) that it does Of course it does because sports outcome are random. Randomness is not the only factor, but it certainly is one.
