The preferable strategy for primary passing teams is to spend a bunch of 2nd and 3rd round picks on RBs like New England did when they took Ridley and Vereen in 2011.
Best plan for the Packers (or any passing team who wants to upgrade at RB) is to wait until day 2. Plenty of good backs are second round picks.
I do agree with the last two paragraphs, and that's why I classify them as dark horses. I would be mildly surprised if they took a RB in the first but it makes some sense.
As for the top, those guys ended up busting (still give Ingram another year) for whatever reason. The Pats have had successful RBs, as have the Colts and Saints. If they didn't bust they would have been good contributors
