Depending on your age group, 6'3 is either kind of short or quite tall. I assume he is the latter
As for high school, the height for centers vary, a lot. I've seen centers from 6 feet to 6'6 or maybe bigger. It depends on a number of factors, don't worry. It's completely about height, skill set also comes in.
I recommend hyperdunks over lebrons since you are looking for efficientcy over looks. Hyperdunks are as good if not better than lebrons efficientcy wise, and is way cheaper. A lot unsponsored NBA players wore hyperdunks as their shoe last year.
As for protection from landing , any shoe with a high cut will protect your ankles, rather than low cut shoes like the KDs which let you ankle move loosely. Either shoe will be fine.
I just ordered myself
NYC edition hyperdunks the other day, very excited. I can tell you about them when I get them.
