i know most of you probably don't follow badminton, but there we have a very interesting situation. Lin Dan, generally regarded as the greatest ever player in history, has spent virtually no time at all as world no. 1. simply because he hasn't played enough tournaments as he likes to dick around at home, relax and enjoy hero status in China. his great "rival" Lee Chong Wei, plays virtually every tournament and is consistently ranked world no. 1. but when the 2 of them meet in the big tournaments, Lin Dan inevitably comes out on top.
its interesting that in the badminton community, most fans are cognizant of this, and so highly discount rankings. i.e. they rely much more on their judgement of real players' abilities. the chinese players for eg, are generally ranked relatively low in world rankings. simply because they don't play enough tournaments. but come the big tournaments like All England and World Champ, no badminton fan worth his/her salt will discount them.
yet in our tennis community, we seem to have vastly different thoughts about this.
