They're probably use a a set of criteria like the last one. I think you had to have under 15 pro bouts in order to qualify in London. They're probably removing that cap but you'd have to figure that:
- You probably cant be a champ/ belt holder, I wonder if the olympic participation will drop your ranking either by law or by inactivity
- Of course testing clean. Same day weigh ins.
- Probably can't bring your own coach or team or gear (except for mouthpiece) to competition.
- You probably have to fight for your birth country or maybe the country you pay the most taxes to . As you have fighters now with dual citizenship. That probably rectifies situations like "sorry the us team is full but i hear Turkey is looking for some hired guns...apply there"
- No endorsement deals, cuz you know the pay alone will keep many of the pro's away.

If its a free for all it will screw the whole sport, even the pros...
