It's also arguably not acceptable. There have been allegations of fairly large amounts of money changing hand for in some of the deals, promoters and sponsors tend to frown upon that stuff, as do sports books and it might be against the law (sporting fraud) in a few European countries. The rules and the codes regarding this sort of thing are fuzzy. There is also a class system of sorts in play. When Lance Armstrong went to the media and claimed he let Marco Pantani win on Ventoux in the 2000 Tour, that's against the code too but because Lance was so dominant nobody said much about it. The fact was, nobody could make Lance pay for that on the road. In the romantic ideal world, a bunch of Italian teams would have worked together to prevent Lance's teammates from winning some monuments (maybe Hincapie at Paris Roubaix, but he was never really in it) that they were targeting but the fact was the team was built for one purpose and that never was an option. The ability to enforce the deal is part of it. Likewise, in retrospect, Lance going public with it was a scorched earth psychological tactic that made his image even bigger. I would say, at least at some levels (u-23 national championship might not be that) that if you can get someone to gift you a win for an unenforceable deal, then you beat them and you did it mentally. It's like all the secret rules of baseball.
