Saints 2013 Draft

I have to say that right now Vacarro projects as the best pick IMO, because he seems so versatile (in a good sense). I'm no expert but you could see him being the "neutralizer" of other team's best receiving threats (excluding outside receivers) and a good run stopper as well. I don't know what FO can expect from Harper now. Thoughts?
I remember reading Cosell and how he sees players like Austin and Eifert as modern playmakers on one side... and safeties like Vaccaro on the other.
