The most cliche term used in all of sports is “chemistry” as it pertains to how personnel on a team meshes together.
Seriously, every time a player joins a new team, the first question people want to ask is “Can they find chemistry? How will they work together? Is this a good fit?”
Nonsense. Absolute nonsense.
This does not mean that it is ideal for players to brawl in the locker rooms before and after games, but the idea that players need to be best friends with each other is a concept that has never existed with any championship team in any sport.
