A quick look at 100 of the top players in this week's NFL draft, as rated by veteran Post-Gazette pro football writer Ed Bouchette:

Quarterbacks

JaMarcus Russell
LSU, 6-5 1/2, 265
Strongest arm in college football will become strongest in the pros.

---

Brady Quinn
Notre Dame, 6-4, 232
Once considered first overall pick, inconsistency dropped him to No. 2 quarterback.

---

Trent Edwards
Stanford, 6-4, 231
Pure pocket passer who's no Big Ben on rollouts.

---

Drew Stanton
Michigan State, 6-3 1/2, 226
Tough, mobile quarterback who can stay in the pocket or throw on the run; arm strength a question.

---

John Beck
Brigham Young, 6-2, 215
Will turn 26 and still needs time to develop but has great intangibles.

---

Running Backs

Adrian Peterson
Oklahoma, 6-1 1/2, 217
Outstanding runner who has a history of injuries, including broken collarbone last season.

---

Marshawn Lynch
California, 5-11, 215
Good size and speed (4.51), he's tough to tackle, a Steelers type of back.

---

Antonio Pittman
Ohio State, 5-11, 207
Best speed (4.38) of all the backs, he's not Willie Parker-like in his quickness or an outside runner.

---

Kenny Irons
Auburn, 5-10 1/2, 203
His senior year was marred by minor injuries.

---

Tony Hunt
Penn State, 6-1 1/2, 233
Best size of the top five, a power runner inside who would be great complement to Steelers' Willie Parker.

---

Fullbacks

Brian Leonard
Rutgers, 6-1 1/2, 226
Versatile runner who can block, catch, run and serve as third-down back as a West Coast fullback.

---

Le'Ron McClain
Alabama, 6-0, 256
Outstanding blocker as a true, old-fashioned fullback who can run on occasion and catch a pass or two.

---

Cory Anderson
Tennessee, 6-2 1/2, 247
Another true blocker who carried just once last season (matching Dan Kreider).

Jason Snelling
Virginia, 5-11, 230
Shown good blocking ability to go with good hands and might develop his running skills.

---

Derek Schouman
Boise State, 6-2 1/2, 247
Played tight end in college and pros might consider him there, an H-back or fullback.

---

Wide Receivers

Calvin Johnson
Georgia Tech, 6-5, 239
Considered best player in the draft and could go No. 1.

---

Robert Meachem
Tennessee, 6-2, 214
Big dropoff after Johnson, but has the ability to become a star receiver.

---

Dwayne Bowe
LSU, 6-2 1/2, 221
Not as speedy as the pros would like, he's extremely productive, a possession receiver for the NFL.

---

Ted Ginn
Ohio State, 5-11 1/2, 178
Foot injury in BCS title game might hold him back, but his speed has held up.

---

Dwayne Jarrett
USC, 6-4, 219
Big-time production at a big-time school, with size to make up for so-so speed (4.55).

---

Tight Ends

Greg Olsen
Miami (Fla.), 6-5 1/2, 254
Another in a long line of outstanding Hurricanes tight ends; just don't ask him to block.

---

Zach Miller
Arizona State, 6-4 1/2, 256
Much slower version of Greg Olsen and, thus, not a game-breaker or a first-rounder.

---

Ben Patrick
Delaware, 6-3, 252
Has the receiving skills of the others without the big-school pedigree, nor quite the size.

---

Scot Chandler
Iowa, 6-7, 270
Former wide receiver whose speed (around 4.8) has been disappointing.

---

Martrez Milner
Georgia, 6-3 1/2, 252
Good speed, inconsistent hands and has displayed little desire to line up and block.

---

Centers

Ryan Kalil
USC, 6-2 1/2, 299
Only possible first-rounder at his position; can step right in and start in the pros.

---

Samson Satele
Hawaii, 6-2 1/2, 300
Strong and athletic, started three years at guard and last one at center.

---

Leroy Harris
North Carolina State, 6-2 1/2, 302
Intense, nasty player who can play at either guard position as well.

---

Dan Mozes
West Virginia, 6-2 1/2, 293
Washington, Pa., native and All-American who started 50 games at WVU, nearly half at guard.

---

Dustin Fry
Clemson, 6-2 1/2, 315
Great run-blocker with strong upper body; a three-year starter.

---

Guards

Ben Grubbs
Auburn, 6-3, 311
The best of an unusually strong group; a former defensive lineman, tight end.

---

Justin Blalock
Texas, 6-3 1/2, 320
Four-year starter who has played at right tackle and could play there in NFL, too.

---

Arron Sears
Tennessee, 6-3 1/2, 319
Versatile player who has started everywhere but center for the Vols.

---

Josh Beekman
Boston College, 6-1 1/2, 313
Can play guard or center, and that's become more important to game-day NFL active rosters.

---

Andy Alleman
Akron, 6-4, 305
Transferred as Pitt DE when former coach Walt Harris declined request to switch him to offense.

---

Tackles

Joe Thomas
Wisconsin, 6-7, 311
Massive left tackle being compared to some of the great big lefties such as Jon Ogden and Orlando Pace.

---

Levi Brown
Penn State, 6-5 1/2, 323
Did not dominate the way Thomas did, but another big left tackle with potential greatness.

---

Joe Staley
Central Michigan, 6-6, 306
Another left tackle, although he's also played on the right; converted from TE as a sophomore.

---

Tony Ugoh
Arkansas, 6-5 1/2, 301
Possible fourth tackle to go in the first round; needs more developmental time than the others.

---

James Marten
Boston College, 6-7 1/2, 309
Has started at guard and tackle; needs to add weight and strength before he can start in the NFL.

---

Defensive Ends

Gaines Adams
Clemson, 6-5, 258
Great pass rusher, as long as he does not get distracted; takes too many plays off.

---

Adam Carriker
Nebraska, 6-6, 296
Can play end in 3-4, tackle in 4-3 and, while the Steelers love him, they'll have to jump higher than the 15th spot.

---

Jamaal Anderson
Arkansas, 6-5 1/2, 288
Poorer-than-expected postseason workouts dropped him slightly, but still a first-round selection.

---

Jarvis Moss
Florida, 6-6 1/2, 250
Plenty of potential as a pass-rush specialist, particularly at right end in a 4-3 defense.

---

Anthony Spencer
Purdue, 6-2 1/2, 261
Has good speed, but lacks the kind of size pros prefer in their ends, so he will have to get bigger, stronger.

---

Defensive Tackles

Amobi Okoye
Louisville, 6-2, 302
Native of Nigeria, entered college at 16 and, after playing four years, will be drafted at 19.

---

Justin Harrell
Tennessee, 6-4 1/2, 300
Overcame torn biceps that ruined virtually all of his 2006 season; could be a steal.

---

Alan Branch
Michigan, 6-5 1/2, 324
Pro day workouts 10 days ago were disappointing and he slipped a little.

---

Tank Tyler
North Carolina State, 6-2, 306
Most improved end on the board from his junior to senior seasons.

---

Brandon Mebane
California, 6-1, 309
Significant falloff at this point; he might be suited more as a nose tackle than four-man DT.

---

Outside Linebackers

Paul Posluszny
Penn State, 6-1 1/2, 237
Injury early last season set him back, but his play returned by the end and he is the best linebacker in the draft.

---

Jon Beason
Miami, 6-0, 237
Height somewhat of a problem, but speed and athletic ability offset it.

---

Lawrence Timmons
Florida State, 6-0 1/2, 234
FSU listed him at 6-3 and his stock dropped when he was measured at combine; lacks great instincts.

---

Stewart Bradley
Nebraska, 6-3 1/2, 254
Ideal kind of player in a 3-4 scheme on the strong side; started three seasons.

---

Tim Shaw
Penn State, 6-1 1/2, 236
Overshadowed by Posluszny, he's moving up based on his speed and his versatility.

---

Inside Linebackers

Patrick Willis
Mississippi, 6-1, 242
Only first-rounder of the bunch; exceptional player and person; a true blue-chipper.

---

David Harris
Michigan, 6-2 1/2, 243
Should play the run-stopper at inside in the 3-4 defense; going forward, not covering, is his strength.

Buster Davis
Florida State, 5-9 1/2, 239
Only negative is his height, but his Jack Russell-like play is relentless and made him All-America.

---

Justin Durant
Hampton, 6-0 1/2, 230
No small school sleeper here; everyone knows about him, including Hampton-area native Mike Tomlin.

---

Brandon Siler
Florida, 6-2, 241
Knock on him is he played behind great linemen; was that a knock on Jack Lambert with the Steelers?

---

Cornerbacks

Leon Hall
Michigan, 5-11 1/2, 202
Compared to another former Michigan great, Aliquippa's Ty Law.

---

Darrelle Revis
Pitt, 5-11 1/2, 204
Aliquippa native whose stock climbed when he ran 4.38 at Pitt's pro day; many mocks picking him for Steelers.

---

Aaron Ross
Texas, 6-0 1/2, 192
Late first-round draft choice; tough player, but not as fast or as well-built as the top two.

---

Jonathan Wade
Tennessee, 5-10, 195
Former receiver and track athlete who has all the skills but just one year as a starting cornerback.

---

Chris Houston
Arkansas, 5-9 1/2, 185
A so-called shutdown cornerback, but don't ask him to come up and tackle a running back.

---

Safeties

LaRon Landry
LSU, 6-0 1/2, 213
(FS) Top 10 pick, he can do it all and should repeat it at the pro level; has size and 4.35 speed.

---

Reggie Nelson
Florida, 5-11 1/2, 198
(FS) Not as fast or as big as Landry, but he has everything else, including great instincts and hands.

Michael Griffin
Texas, 6-0, 202
(SS, FS) Hard hitter who can play either position in the pros; played free safety next to twin brother Marcus at strong.

---

Brandon Merriweather
Miami (Fla.), 5-10 1/2, 195
(FS) Extremely talented, his disappointing season and one-game suspension for melee with FIU hurt him, but he's climbing again.

---

Eric Weddle
Utah, 5-11, 203
(SS) Started 45 games in his career, 21 at cornerback and 18 at strong safety.

---

Punters

Adam Podlesh
Maryland, 5-11, 202
Might be drafted as high as third or fourth round; quick with good hang times.

---

Daniel Sepulveda
Baylor, 6-3, 229
Big, booming kicks but he's no Chris Gardocki, he doesn't get them away quickly.

---

Kickers

Mason Crosby
Colorado, 6-1 1/2, 212
Cream of the crop with a powerful and accurate leg.

---

Justin Medlock
UCLA, 5-11 1/2, 201
Lefty with a strong leg that's more accurate long-distance than short.

---

Nick Folk
Arizona, 6-1 1/2, 225
Also punted last year; could be the third kicker drafted on the second day.
