When building a team, don't look for the best people, look for the right people.

"Best" here meaning a context-independent measure of quality and skill.

"Right" here meaning the context-dependent measure of applicable quality and skill.

Different contexts require different skills.

You could find the best person in a dimension that is the wrong dimension for this context, which would be the wrong person.

If you're an individual, you want to be the best–good in a lot of different dimensions, more likely to be the right person for a lot of different scenarios.

But if you're a team looking to add a team member, you want to find the right person.
