The key points:
- Hire people who are awesome
- Fire people who aren't
I know a sporting example might not be overly popular on HN, but let me try! In the NBA draft, teams will choose between drafting to fill a need (e.g., they're weak at centre, so they'll draft the best big guy), or drafting the most talented player still available (e.g., a brilliant point guard even though they already have two).
In this hiring context, it's a bit like drafting on talent alone - take the "A Player" and worry about the details later. In the NBA example, this means trying to force a fit (shifting a SG to SF), trading them for things you do need (an elite SG for a decent big and a roleplayer), or rebuilding your team around them.
Michael Jordan was drafted third in 1984. The first pick (Olajuwon) was a top-tier talent but the second pick (Bowie) was a bit of a bust. Portland took Bowie ahead of Jordan because they already had Paxson and had recently drafted Drexler.
