Or so I presume since we already know Exum won't be a bust. As a teenager, he's already shown enough potential to ensure that doesn't happen, barring catastrophic injury.
Russell on the other hand appears to be more NBA ready...but then again...we all that of Burke...and of Jimmer. Now that you mention it, I think I stick with Exum. He may take some time...but I've seen his potential in the actual league. Great point. Thanks for raising that.
