He might be...but using a highlight of 1 dunk, that most D1 level college players could do, doesn't do much to prove your point. Leal can dunk, very, very easily. You should know that, having watching him both in high school and college.
Hemenway looks to be a little bouncier, lighter on his feet a little bit. But its not a very big difference. Leal is quite a lot more athletic than most give him credit for. Its actually what allowed him to win Mr Basketball, and probably why he got recruited to IU. He was not an elite shooter in HS, or in AAU. He was a "triple double" type of guy, that used his size and strength advantages as a guard well.
I think Hemenway is actually fairly redundant to Leal. If I were Woody, I'd get that foreign kid as a back up big. And keep the last spot open for maybe another big that might pop up in the next couple days as an option.
