What Makes a "Strong Player"?

From Agile Principles, Patterns, and Practices in C# by the Martin duo:

“A strong player is not necessarily an ace programmer. A strong player may be an average programmer but someone who works well with others. Working well with others—communicating and interacting—is more important than raw programming talent. A team of average programmers who communicate well are more likely to succeed than is a group of superstars who fail to interact as a team.”

Amen to that.
