I would put a slightly different twist on that. A team with diverse skills and a lot of mutual trust and respect will work wonders. My current group is what you might call "debug fire jumpers" (not 100% of the role, but a significant fraction of it). Knowing I can call in an expert in an area that I am fuzzy, and there is no judgement, and we can collaboratively solve the problem, is what enables the team to deliver. So I fully agree, building a team with mutual trust and respect is the first order of business.
