The following is the third in a series of scouting reports for draft prospects who are participating in this year's Senior Bowl. These reports from PFW draft analyst Nolan Nawrocki will be running all week leading up to Saturday evening's game in Mobile, Ala.

DE-DT Quinton Coples, #90
North Carolina
Height: 6-5 3/4 Weight: 281 Speed: 4.75e
Arm: 33 1/8 Hand: 10 1/8 Age: 21

Notes

Last name is pronounced “COE-pulls.” Spent a year at Hargrave Military Academy (Va.) before playing 12 games as a true freshman in 2008 — was credited with eight tackles, 3 1/2 for loss and 1 1/2 sacks. Played all 13 games in ’09 (one start at defensive end) and notched 22-6 1/2-5. The suspension of Marvin Austin prompted Coples’ move inside in ’10 when he started 12-of-13 games and produced 59-15 1/2-10 with two passes batted down and two forced fumbles. Made all 13 starts at left defensive end in ’11 and led the team in tackles for loss and sacks after posting 55-15-7 1/2 with two batted passes and three forced fumbles.

Upside

• Excellent body length
• Exceptional athlete with terrrific balance, bend and body control
• Has a long second step, great closing speed
• Can stack the line — solid run defender
• Versatile 

Downside

• Rises off the ball, negating takeoff speed
• Idle motor — too many backside loafs
• Shut it down as senior
• Questionable makeup
• Relies too much on natural ability
• Average competitor 

The way we see it
An extremely athletic, versatile, inside-outside pass rusher capable of dominating, Coples too often plays down to the competition, coasts on his given talent and fits the classic underachiever label. A boom-or-bust pick who might be affected by a big payday.
