Interesting theory, but in software development, doesn't the B player learning from the A player raise the abilities of the B player? I've learned a ton from A player developers, though I am not convinced I will ever be one, they have definitely helped me. In comparison to the Korean Pilot example provided, software development is rarely a life and death situation, where the silence of a B player will result in the downfall of the product. We luckily have the opportunity to do a test run and make sure everything works as we expect it to. Lastly, how many people agree that idea guys are B players. I'll admit, I'm an idea guy and as I already stated, I figure I'm a B player, but I didn't think there was a relationship between the two. Thankfully, ideas guys can be as valuable as A player developers.
