Greg Oden: Why the Lefty FT's?

I tuned in to Ohio State-Cinci today to get another look at the Hoff Bros. (my brother Drew and I) pick to win it all, and was treated to the usual slashing from Michael Conley Jr., shooting from Ron Lewis, and all-around sensational play from the underrated Daquan Cook. And of course, dominant play in the paint from Greg Oden.

One thing left me puzzled though: why is Oden still shooting free throws with his left hand? I admit it makes for a fun story. I mean, we can take a trip down memory lane and remember Bo Kimble's tribute in the 1990 NCAA Tourney. We can talk about how Oden is shooting better with his off hand than Shaq does with his strong one. It speaks to Oden's work ethic and skill level and blah, blah, blah. But why is he doing it?

He throws outlet passes with his right hand. He blocks shots with his right hand. And he throws down monstrous, thunderous dunks with his right hand. All of those things would seem to be more taxing than shooting a free throw. Is it the bending of the wrist on a 15-foot shot that presents a problem? Is it because there is time to think on a free throw as opposed to just reacting and playing through pain with the rest of the stuff? Consider me curious. It's great that everyone under the sun is mentioning that this is happening, but just once I'd like to hear why.
