While it's not a sure sign that these players will be the first 17 players selected, expecting it to be the players actually invited to attend the draft is as good a sign as any. Here's the unofficial list from Pro Football Talk:
Auburn quarterback Cam Newton, Cal defensive end Cameron Jordan, Texas A&M linebacker Von Miller, Alabama receiver Julio Jones, Iowa defensive end Adrian Clayborn, Alabama running back Mark Ingram, Missouri quarterback Blaine Gabbert, Georgia receiver A.J. Green, Wisconsin defensive end J.J. Watt, Missouri defensive end Aldon Smith, Clemson defensive end Da’Quan Bowers, Auburn defensive tackle Nick Fairley, Nebraska cornerback Prince Amukamara, and Alabama defensive tackle Marcel Dareus.
Of course, the most famous drop in Green Bay Packers/NFL draft history is QB Aaron Rodgers. The Fifth Down blog has an excellent recap of the entire story. Lucky for Packer fans, former 49ers head coach Mike Nolan is a poor judge of character when it comes to selecting a starting quarterback. At the bottom of their article is the entire first round with all the players selected ahead of Rodgers. There was a whole lot of fail drafted ahead of him.
