Underrated comment & stated beautifully.

If you want a "diverse" team, having both kinds of above stated people on the team is crucial. The above mentioned A players can't do the steady boring work the so called C players can do & likewise that the C players can't do what the A players can. Also C players can be great at questioning all the bleeding edge new tech A players want to implement. For reasons like this, I think it's important that more senior positions are made up of both kinds of people.

Good managers will help everyone identify which kind of person they are & help them have work that fits them best. They'll keep the C players motivated & the A players feeling challenged.
