I'd agree with you, kmason, if we were talking bigs, but for my money, you need to run the court for the 1-2-3. Can't use that athleticism if you can't keep up with the guy you are guarding. The guy above would be out of position chasing faster guards alot of the time.
In rethinking it, I'd actually swap ath and d (sp/ath/D). D is important, but if you understand that it doesn't mean defensive ability, but rather the desire to play defense it becomes much less important than the other two. I say this with the caveat that I'd never take a guy with low defense anyway, I'd just take a guy with 50 D and high spd and decent ath over any slow guy with high d.
