I've never done a mock before, being content to comment on others. Well, finally, here is my first ever mock.
1. Cordy Glenn, OL, Georgia: I'm hoping that Glenn falls and the Steelers get a big, versatile offensive lineman. If Glenn is off the board and the Steelers stay at 24, I think I go with Hightower.
2. Derek Wolfe, DE, Cincinnati: Wolfe has the prototypical size and athleticism that you look for in a 3-4 DE. I'm hoping for an athletic, disruptive end in the mold of Aaron Smith (note: I'm not saying that he'll be the next Aaron Smith). Keisel is getting older, and the Giants are a great testament to the value of rotating defensive lineman. With Wolfe, Hood and Heyward, Steelers are set at DE for the future.
3. LaMichael James, RB, Oregon: Speed back is a nice complement to Redman and the rest of the stable of Dwyer, Clay and, when healthy, Mendenhall. May not have the size to be an every down back, but Haley can incorporate an explosive player and balance his carries.
4. Lucas Nix, OG, Pitt: This is the pick regardless of Glenn or Hightower in the first. Nothing flashy, but he'll be a solid RG.
5. Hebron Fangupo, NT/DT, BYU: May be a round early, but the Steelers decide to roll with another defensive lineman from BYU.
6. Evan Rodriguez, TE, Temple: Versatile TE has both blocking and receiving ability.
7. Toney Clemons, WR, Colorado: Decent side and speed, worth a shot as the #5 WR, possible development project.
7a. Akiem Hicks, DT, Regina: Project with lots of physical tools. Somebody may gamble on him earlier, but if available, worth a shot.
7b. Jeremy Jones, S, Wayne State: D2 guy showed some ball skills with plenty of picks in college.
7c. Jerrell Harris, LB, Alabama: Likely a PS candidate, he may be able to contribute on special teams as a rookie.
The hardest omission from me was Brandon Brooks from Miami of Ohio. I wanted to find a way to work him into the draft, and was thinking of going with Hightower/Brooks 1/2, but I decided that I wanted Wolfe just a bit more.
