Avichal Garg, co-founder of Spool (www.getspool.com) writes an amazing post on focusing on teams, not #s of developers or hiring just for best available athletes.
Focus on building 10x teams, not on hiring 10x developers
There are a lot of posts out there about identifying and hiring 10x engineers. And a lot of discussion about whether or not these people even exist. At Spool, we’ve taken a very different approach. We focused on building a 10x team.
We believe that the effort spent trying to hire five 10x developers is better spent building one 10x team.
