You can't find the best team. The best teams don't just happen because you recruit all of the best skilled people. The one constant you will find if you research the "best teams" is they always have a great leader. A great leader is the key element to the best teams. A great leader can and will make any team great. A great leader will find the strengths and weakness of all people who are part of the team and put them in the position to be their best. The leader doesn't always have to be the "boss" the leader is as the word states the leader of the team. The leader is a person the entire team trusts, supports, believes in, respects and leads by example. There are millions of great team members but very few great leaders, so easiest answer to this question is simply find a great leader and let that leader build the best team.
