This is a common problem with folks who start in management roles right after college. It sounds incredibly trivial, but you have to kinda be on the other side ... "be managed", to better understand the difference b/w good management and bad.
I also had some very incorrect paradigms about the world which I was able to correct in the first couple of years of work (and which I continue to do today whenever I find them to be wrong). Not having the opportunity to do so is a great disservice to these folks... they may never realize some very simple things that most people find rather trivial but they seem to have great difficulty understanding.
e.g. that person who never responds to emails. If I were to guess, it sounds like he has a very inflated sense of self (not common right after college, especially from a top university). It is likely he thinks whatever he does is AWESOME and the boss will realize this and he doesn't need to communicate with the rest of the team.
