Scouting Report / Defensive linemen
Best of the best
Quinton Coples, DE, North Carolina
6-5 3/4, 284, 4.78
Comment: Top-15 talent. As physically gifted as any 2012 prospect, any position. Tremendous footwork and hands. Excelled at Senior Bowl and in certain combine drills. Has the look of a dominant player. But will he buy in mentally on every snap? By his own admission, he did not play as well as in junior year. Does he wants it badly enough? At least one team in first half of first round will be sure it can maximize his vast potential.
Fletcher Cox, DT, Mississippi State
6-4, 298, 4.79
Comment: Top-20 talent. Has steadily moved up boards in off-season. Dontari Poe of Memphis received more publicity for his Herculean combine, but Cox also put on a show. He looked especially good in agility drills. Quickness and length (34 1/2-inch arms) make him difficult to handle at the point of attack. Cox also can play end. Scouts think his frame can add more pounds without sacrificing agility. Intelligence and instincts enable him to play different schemes and techniques at a high level. Former NFL standout Warren Sapp is one of Cox's biggest fans. 2011: 56 tackles, 14.5 TFL, 5 sacks.
Best of the rest
Nick Perry, DE, Southern California
6-2 3/4, 271, 4.64
Comment: First-round talent. One of best pass rushers in draft. Relies on physicality, quick hands and multiple moves to beat his man. Highly motivated, having come from poverty in Detroit. Great work ethic. Had 38-1/2-inch vertical jump and 35 reps at 225 pounds at combine. Got better as 2011 season progressed, finishing with 9 1/2 sacks. Did nice work against Stanford's Jonathan Martin. Needs to improve against the run. Projects as 4-3 left end in NFL.
Michael Brockers, DT, LSU
6-5, 322, 5.36
Comment: First-round talent. Brockers admitted he was a bit nervous at combine, and it showed. His speed and strength numbers in Indianapolis were pedestrian. He was much better in all areas at his pro day, including 5.15 in 40. Brockers, one of the youngest in his draft class, is athletic and long (35-inch arms). Played well against quality competition in his one year as a starter. Strong, with quick hands. Still considered raw.
Courtney Upshaw, DE, Alabama
6-1 5/8, 272, 4.76
Comment: First-round talent. Somewhat of a 'tweener: Will he be 3-4 rush linebacker, which he played at Alabama, or 4-3 end, which he did in sub packages? The more scouts look at tape, the more they see him as a right end in NFL, in part because of his questionable cover skills. Thick lower half. Has boxer's hands and accelerates off block. Played in elite program against good competition. Needs to show more explosion to quarterback.
Jerel Worthy, DT, Michigan State
6-2, 308, 5.08
Comment: First team AP All-American. Quick off the ball -- clocked 1.64 in 10-yard split at combine -- then relies on brute strength. Can push the pocket. Played superbly in Big Ten championship game against Wisconsin; did as he pleased against Badgers' vaunted line. Evaluators want to see something close to the Wisconsin game on a more consistent basis.
Devon Still, DT, Penn State
6-4 7/8, 303, 5.08
Comment: Often mentioned in same conversation as Worthy, in that both are Big Ten products with immense physical gifts who can impact games but struggle with consistency. Showed good bursts off line at combine. Periodically relies too much on arms. Still and Worthy could argue that their game tapes, even with the glitches, are better than most.
Others to watch
Kendall Reyes, DT, Connecticut
6-4 1/8, 299, 4.95
Comment: Could end up being one of biggest value picks in draft. Playing under the radar at UConn. Scouts think his best football is ahead of him. Excelled at Senior Bowl and performed well at combine (36 reps at 225 pounds). Fierce competitor. High football IQ and character. Coachable. Technically sound.
Dontari Poe, DT, Memphis
6-3 1/2, 346, 4.98
Comment: Projected first-round pick. Dazzling performance at combine featured 44 reps of 225 pounds. Strength and agility for his position have drawn comparisons to Baltimore's Haloti Ngata. However, game tapes showed an inconsistent player who took plays off and spent too much time on the ground. Stock has fallen from top-10 immediately after combine, presumably as NFL evaluators study more game tapes.
Chandler Jones, DE, Syracuse
6-5 3/8, 266, 4.87
Comment: Natural edge-rush ability. Tall, with long arms (35-1/2 inches). Can drop into coverage. Leg injury limited 2011 season to seven games and hampered his impact. Has room to fill out the frame. His defensive coordinator at Syracuse was former Northeast Ohio football standout Scott Shafer.
Vinny Curry, DE, Marshall
6-3, 266, 4.98
Comment: Underrated. Amassed 40 tackles for loss last two years. Speed and size are not prototypical, but he is reasonably quick, especially with the inside move. Knows how to get to QB. Uses hands well to control blockers. Decent edge quickness. Low-risk, high-reward pick if he's available in third round.
Jared Crick, DE, Nebraska
6-4 1/4, 279, 4.99
Comment: Torn pectoral limited him to five games in 2011. Had 9.5 sacks in each of previous two seasons. Big hands. Smart, competitive, relentless. Durability is an issue.
On the Browns
Starters: Jabaal Sheard (LE), Phil Taylor (DT), Ahtyba Rubin (DT), Frostee Rucker (RE).
Backups: Juqua Parker (DE), Auston English (DE), Scott Paxson (DT), Brian Sanford (DE/DT), Brian Schaefering (DE), Marcus Benard (DE), Kiante Tripp (DT), Emmanuel Stephens (DE).
Level of need (1-10): Two.
Comment: One of the deepest positions in draft also happens to be deepest position on Browns other than kicker/punter. Browns added free agent Rucker to fill spot vacated by Jayme Mitchell. Browns also signed veteran Parker to bolster a line that features young starters in Sheard, Taylor and Rubin.
If Browns choose to draft high for a defensive linemen this year, something must be wrong with their recent talent assessments. Odds are that, by the time they do take a D-lineman, he won't be one of the bigger names. Keep on eye on Michigan DT Mike Martin as a possible value pick.
