OK, here's my Steelers mock. I'm using a draft engine to make the rest of the selections, so I am only going with who is available under those auspices at each pick (just so I am not biased and make selections for other teams based on who I want to see fall for us..)
1. Jesse Williams, NT, Alabama - a (very) slight reach, but the Steelers are not afraid to take a player they like. I think this guy is an ideal fit for them. For one, he anchored the line for a national champ, and the Steelers love to draft guys from successful programs. Two, he has nimble feet and tremendous strength - profiles as the draft's best two-gap nose, but could also theoretically slide out to the 5-technique if for whatever reason he can't handle the middle, so he's not a "boom or bust" pick as many 3-4 NT prospects are. McClendon is signed to a deal that's likely a 2-year deal and Ta'Amu has size and talent but it doesn't appear he has the drive and maturity to inherit this pivotal spot in the LeBeau defense.
2. Khaseem Greene, ILB/OLB, Rutgers - a versatile LB with a nose for the ball and big plays, Greene is a better football player than he is a pure athlete. I think his best fit is as a weak-side guy in a 4-3, but frankly, I've watched every game he's ever played and I think he can succeed anywhere. His transition from S to LB showed rapid improvement, as evidenced by his back-to-back Big East DPOY awards. He's an outstanding pursuit linebacker that plays best covered-up, so he's not a great scheme fit (but neither was/is Sean Spence) but the guy flat makes plays. He can do a little of everything - rush the passer when he has a lane, drop back into coverage and stick with RBs/TEs, or lay the lumber on a back who gets across the line in run support. I have it on good authority that the Steelers have expressed strong interest while keeping said interest largely off the national radar.
3. Marquise Goodwin, WR, Texas - look, I've picked this guy to the Steelers in round 3 in both Shark Pool mocks, so I'm not stopping now. This guy is a day 3 prospect in the minds of many and if the Steelers do take him here, the word "reach" will be thrown around quite a bit. However, if they draft a receiver on day 1 or 2, what they're going to be looking to replace is Wallace's dimension to the offense. There's probably no closer comparison to Wallace in this draft than Goodwin. Slightly undersized? Check. Very little collegiate production? Check. Impressive post-season/Senior Bowl performance? Check. Blinding, top-of-the-class speed? Check. I know he's a project, but the Steelers contstantly make a point of saying they don't expect rookies to contribute immediately except on special teams. This guy replaces Wallace's speed dimension, gives Haley the bubble screen/end-around/gadget play guy he loves to have, can contribute as a return guy right away. I hear a lot of chatter that teams looking for the next Wallace are zeroing in on this cat and that he won't last until Saturday.
4. Shawn Williams, S, Georgia - doesn't have great hands and isn't much of a ball-hawk, but can lay the wood as a run-supporter and is a gritty and competitive guy. Sounds a hell of a lot like Ryan Clark, the guy he'd be replacing. An underrated player who was overshadowed by a few others on his own defense at Georgia that I'm not convinced will be better pros.
5. Joseph Randle, RB, Oklahoma St. - here's a guy whose stock seems to be slipping and whose name is not being mentioned as a possible day 1 or 2 pick. Polarizing prospect who some hate and others think can be Adrian-Peterson (very) Lite in the NFL. He has the production in college to back up those that like him, he has adequate speed and wiggle, even if he's not a pile-moving kind of back. If we retain Dwyer or Redman, though, we already have that. He's a guy that can be had on day 3 that can take limited carries and learn from an Ahmad Bradshaw, and has the upside to be a starter and at least a 2-down feature TB in a year or two.
6. Travis Johnson, OLB, San Jose State - developmental prospect at OLB if Worilds doesn't pan out. Way undersized and is likely to get manhandled by bigget NFL tackles, but he does have quickness and is a relentless, high motor, intelligent player. An Eagle Scout and high character guy, you can bet on one thing, he will bust his butt to become an NFL player. Strictly a 3-4 OLB, he won't be in as high demand, but has some upside this late.
6 (comp). Corey Fuller, WR, West Virginia - I've seen Fuller go as high as the 4th in some mocks, so I doubt he's still here in the late 6th, but in this case, he was. Weak, undeveloped, and a huge question mark, those concerns could possibly push him this low. He does have excellent raw athletic ability and a good size/speed ratio at 6'2" and 4.4. A project to be sure, but one worth taking on this late.
7. Johnny Adams, CB, Michigan St - a tough kid with limited size and speed but plays with a mean streak and is a solid tackler. Profiles as a slot corner only but could make the roster.
