Bad Wigins, many timeds you write something right and interesting, but this time you pissed out of the basin.
In any international competition, the praxis is as follows :
1) Before the technical meeting, the officials of every Country need to go to the technical committee showing pictures of the official uniform of the team. Every athlete without the official uniform is not allowed to compete.
2) Every athlete MUST wear the official singlet of the National Team, normally coming from a technical sponsor, and can't wear anything else.
3) Every athlete having a personal contract with some technical company MUST use shoes of that company.
4) Before going on the track for the race (or the comptition in other technical events) in the call room all the athletes have to show their singlet, which must be the same of the pictures. The judges control shoes, too.
If an athlete decides to compete using shoes from another Company (different from the one gived him the contract), he MUST cover all the logos, and the shoe has to become Anonymous.
5) In many competitions, there is a transponder with a code inside the bib, used for the splits every 200m (this was the case during the last WCh, probably during this ECh too), so nobody can remove the number.
6) And, finally, how already I explained, to compare what athletes do AFTER finishing their competition (such as some sprinter, or Harting, for example) with what an athlete does INSIDE the competition, is completely unfair and wrong.
And, personally, I don't agree all the stupid celebrations made by players after a goal. Athletics is still a serious sport, not something as soccer, that, at top level, in too many case becomes "oppium for people", and has nothing to do with sport (or do you think that spectators gunning a referee, or fighting each another during a match, or throwing fires on the field during the match, or insulting black players, have something to do with the principle of a real sport ?).
Sorry if the worst attitudes of soccer players go to ruin the brain of some athlete.
Many years ago athletics was the "mother" of all the sports. Reading your words, it seems you want now athletics as the poor and idiot nephew of sports that look at the image more than at the real moral and educational values.
