Isn't that opposite of what you'd expect? I'd expect in general for people to think their part is the easy part, and the other part is the hard part. After all, presumably that's why the execution guys can't come up with the ideas, and the idea guys can't come up with the execution. If the other part were easy they'd do it themselves.
