the trouble is there are several, or at least several that one can interpret as "league ratings". UEFA puts out the only ranking that has any concrete application. it determines how many CL and EL spots each league gets. but look at the tab "club coefficients" which is behind it and you"ll see plenty of room for argument. not that the UEFA rating system is daft: basing it on actual results is objective, and using the last 5 years gives it a (perhaps overgenerous) measure of stability. That's all good for their purposes but clearly doesn't answer ours. rating systems like that done by IFFHS are more immediate, but no more useful. proof? first read the article that says the MLS is rated 77th. then follow the link to IFFHS it provides, and you'll find the MLS is 42nd... for now. look it two weeks it might be 30th... or 80th. now that's daft. somewhere on the guardian (perhaps the fiver) they do a rating (whether club or country i don't remember) boxing style: if you beat the champ, you're the new champ. the results are zany. just to prove (as i imagine it's intended to) that no rating system can ever be truly reliable.
