All we need is some evidence of 1* players with poor ratings...although that could merely be evidence that they were exceptionally poor in that match.
I'm not saying this is certainly how it works, but whenever I've played 3* players, their ratings have been good, but they've actually done very little, if judging my the commentary.
Of course, there is a good argument that the ratings mean very little, anyway. I've certainly had players block 6-7 shots, score a goal and get a 5, or 'keepers who save a few 1-on-1's, corner headers, etc, who got a the same rating. I have no doubt many others have had similar experiences.
