Tangor: There is one other difference between your site and theirs. Theirs are already ranking top [x].
Nobody here has said ONLY go after the links they have. What Mr. Ogletree has stated, quite correctly, is that by researching their links you can cherry pick from them. Add those cherries to your own DIY link building processes, and you have just beaten then in the SERPS.
Another added benefit from solid research is simply to see what pitfalls they have gotten into, thus avoiding said pitfalls yourself.
This is not a difficult topic to understand folks...
