> you'd be surprised how many people look decent on paper but somehow can't write a line of code without some serious hand-holding

I think a lot of this may have to do with nerves. Writing code on a whiteboard when given an arbitrary question is very different than writing code in a comfortable context and environment. I think it's safe to say that a decent percentage of people in our field let nerves affect their ability to write quality code at the same level they normally do.
