Will Jadeveon Clowney join group of fast DEs who fizzled?


Jadeveon Clowney's 4.53-second 40-yard dash elicited a jaw-dropping response, but that kind of speed from a defensive end hasn't necessarily translated into individual NFL success of late.

Clowney's 40 time is tied for sixth among all defensive linemen at the combine since 2003, and the guys who have run faster (or just as fast) haven't done all that much in the NFL, with an exception or two.

Important to note: While some of those players moved to linebacker in the NFL, they were classified as defensive ends at the combine. Perhaps more important to note: Clowney (who measured 6 feet 5¼ and 266 pounds at the combine) is considered a vastly better prospect than the guys on this list, though one of them was a first-rounder.

Here's a look at the aforementioned six other defensive linemen:

1. Manny Lawson, N.C. State

Time: 4.44.
Draft: 1st round (22nd overall), San Francisco.
Buzz: Lawson (listed at 6-foot-5 and 240 pounds) is with Buffalo, his third NFL team, and he has been a starter throughout his career. He has 22 career sacks, with a single-season high of 6.5 with San Francisco in 2009. He also has 404 career tackles, with a career-high 73 last season. Lawson also has played for Cincinnati.

1. Isaac Hilton, Hampton

Year: 2004.
Time: 4.44.
Draft: 7th round, New York Giants.

3. Marcus Howard, Georgia
