The phrase “team chemistry” has been tossed around so often that it has earned a prominent spot in the Hall of Fame of sports clichés. But for the life of me, I had no idea what the term represented. Was it a function of how long a group of athletes had been playing together, and how well they could anticipate their teammates’ next moves? Was it a measure of how well their strengths offset their weaknesses? Or was it a reflection of how much everybody on the team liked one another and how splendidly they got along?
