Let me start by saying that I know nothing about the big wresting leagues I see on American TV, I've seen them on a couple of times. A couple of things strike me:
- Some of the "moves" they do are potentially very dangerous, this implies that the wrestlers have at least some understanding of the moves which are coming and how they can avoid becoming seriously injured.
- There is certainly amateur wrestling around which is a serious competitive sport therefore there must be some improvisation/competition.
When we watch a big wrestling match on the television with the top wrestlers how choreographed is the fight (for safety and entertainment reasons) and how much is genuine competition (like boxing)?
