Steelers Lounge has a new post up that isn't exactly a mock draft, but actually is somewhat better - it's a list of players the Steelers could potentially pick in each round, along with a guess at that probability that each will still be there when they pick. Here are their lists for the first and second rounds:
1st round (31st overall)
OT Gabe Carimi, 6-7, 315, Wisconsin, 25%
OT Derek Sherrod, 6-5, 320, Mississippi State, 50%
DE Cameron Heyward, 6-5, 295, Ohio State, 45%
CB/FS Aaron Williams, 6-0, 205, Texas, 55%
CB Brandon Harris, 5-10, 190, Miami, 60%
OT Nate Solder, 6-8, 320, Colorado, 30%2nd round (63)
CB Curtis Brown, 6-0, 185, Texas, 45%
OT/G James Carpenter, 6-4, 320, Alabama, 45%
RT/G Ben Ijalana, 6-4, 315, Villanova, 40%
G Danny Watkins, 6-4, 310, Baylor, 25%
CB/FS Ras-I Dowling, 6-1, 200, Virginia, 35%
G/RT Clint Boling, 6-5, 310, Georgia, 40%
OG Rodney Hudson, 6-2, 300, FSU, 50%
OG/RT Marcus Cannon, 6-5, 360, TCU, 35%
DE Christian Ballard, 6-3, 285, Iowa, 40%
WR Greg Little, 6-3, 230, North Carolina, 55%
G/OT Orlando Franklin, 6-5, 315, Miami, 30%
CB Johnny Patrick, 5-11, 190, Louisville, 60%
WR Jonathan Baldwin, 6-5, 230, Pitt, 35%
ILB/OLB Martez Wilson, 6-3, 245, Illinois, 40%
Even with a list as conditional as this one, there's a lot to debate. For example, most mocks I've seen recently don't have someone like Dowling lasting after the first 45 picks or so, and yet we know the Steelers are interested, because they brought him in for a pre-draft visit. It seems at least possible that the Steelers could take Dowling in the first round. I also don't think it seems nearly as likely as Steelers Lounge does that Carimi, Sherrod or Heyward will still be available when the Steelers pick in the first round. (Steelers Lounge does note that this list is like a "wish list.") Nonetheless, this is an interesting list that provides a good general idea of what the Steelers could be thinking, and who might be available to them.
