A theoretical match up. Who will win?
Bob and James.
Same weight, same height, same endurance, same strength.
No weapons. No grabbing any physical object in the environment and using it to their advantage.
Bob is a hardened criminal who's been to 100 street fights and ended up killing 50 people in 50 of those fights. The rest are him winning but not killing, him losing but surviving, or a stalemate. James is an elite mixed martial artist who although only had 5 total professional fights, have actually sparred against 100 people in varying fighting styles with whatever rules thrown at him and ended up dominating in 50 of those 100 fights.
Bob is the aggressor and he wants to mug James. James, recognizing Bob is a legitimate threat, decides to not hold back.
The setting is an empty parking lot noon time.
Both are physically fresh. So it's not like James just got out of an exhausting sparring session or Bob is sore from lifting weights.
Bob is a Catholic, James is a Protestant. It matters. It just does.
How do you think it will play out?
