Clearly we don't look like a slam dunk for Hubbard. But if he did come to Iowa I could see a Hubbard, Basabe, White front court. Will it be short on height? Yes. But it will be athletic and longer than people would imagine.
People are talking about Dwight Howard. Well, if Dwight Howard showed up in college, Iowa's 6'5", 6'7", and 6'8", front line would be vulnerable. But I don't think Dwight Howard is showing up any time soon.
Add Gatens, May, Marble, and Ogelsby to that group and you have strong size at the two. The one doesn't look likely to be a spot of height for Iowa, it might be good to have someone who could stay with a quicker guard.
Seriously, there have been plenty of great NCAA teams that didn't play with a true 5. If you have tough quick guys on the front line you can collapse on a guy with a height advantage.
