What people don't understand, is that even a guy like Ron Artest put up like 40 points in a street game without trying last week. These are Nba players, most of them have already dominated both the High school and college games, so without trying they can easily score on people who are considered prodigies or highly rated prospects. People forget even scrubs like Adam Morrison were capable of things like this in college.
A guy who's a borderline star in the Nba playing against a Hs player is the equivalent of a 17 year old, playing an 8 year old and simply scoring whenever they go into the post.
Whenever Wall performed a crossover it looked like he could have gone to the rim whenever he felt like it.
