It's going to be a linemen heavy draft IMO. As you can see I predicted that 18 of the first 32 picks will be either O or D-linemen. I think that is going to push down cornerbacks where quality may be had deeper into this draft than normal.
Over the past 5 years, on average there have been 8.6 cornerbacks taken in the first 2 rounds. My mock only has 6. A lot of that has to do with the lines being addressed. In that same span, on average 19 linemen have been taken in the first 2 rounds, I have almost that number taken in Round 1. Not including the 7 more I have in Round 2 being taken. So if that prediction holds true, that means 6 players that "on average" would be drafted in the Top 64 picks won't be. Could very well include a couple of corners.
Now I can't definitively say that the CB class will be hurt, but this draft is also relatively strong/deep/top-heavy at LB and S as well. And there isn't a lot of separation between the widely-viewed 2nd best corner (Kyle Wilson) and the guy that may be the tenth best (which is Spievey by NFP's rankings), so I'm not sure teams will be in a rush to get corners early.
Now obviously, I can't accurately predict when runs will occur at any position in the draft. And it's certainly possible there will be a run on CBs in the middle to late part of Round 2, or at the beginning of Round 3, preventing the Falcons from getting the guy they want/like at #83. We shall see.
The fates of Leigh Bodden, Dunta Robinson, and Antonio Cromartie I think will have a large impact on the CB class.
