I am not sure that any of those picks would surprise me that much.
These would be surprises to me:
Eddie Lacy RB Alabama - if they took him it would be a fit as a power runner but there would likely be other equally graded players of higher need
Margus Hunt DT SMU - he is a bit old and needs more time to develop
Keenan Allen WR California - I would be surprised if he made it to our pick and then if he was taken over a DL or DB
Alex Okafor DE Texas - seems too much like Harralson who is already on the roster to fill the role, not at #31
Johnathan Hankins DT Ohio State - the questions about effort and consistency don't fit the Harbaalke profile to me.
