I remember having a conversation with a co-worker when Coach Rose announced that Alan Hamson would be walking on. It went something like this.
Co-worker: "Why would you want to take a kid who only averaged like 10 points a game in high school?"
Me: "Have you ever seen someone who is a legit 7 feet tall?"
So the question still stands: Have you ever seen 7-foot-tall person? They are huge. And Alan looks even taller because of how thin he is (he is listed at 215 pounds).
