Bo Jackson is widely regarded as one of the greatest athletes sports has ever seen. The 1986 NFL Scouting Combine proved that when he ran a hand-timed 4.12 40-yard dash, which was the fastest in the event's history.

2. Calvin Johnson
Measuring in at a ridiculous 239 pounds at the 2007 combine, Calvin Johnson is nicknamed "Megatron" for a reason. The Lions receiver wowed scouts with an insane 11 feet, 7 inch broad jump.

3. Vernon Davis
Tight ends shouldn't be able to move like Vernon Davis does. At the 2006 combine, Davis ran the 40 in 4.38 seconds, helping boost him into the top 10 in the draft.
4. Chris Johnson
Not many prospects helped their draft stock at the combine more than Chris Johnson. CJ2K blurred to a 4.24 seconds in the 40 in 2008.

5. Jadeveon Clowney
Throughout his junior season, Clowney was the consensus No. 1 overall pick, and the 2014 combine was his time to cement that status. The South Carolina product ran the best 40 time of all defensive linemen with a 4.53 seconds.

6. Dontari Poe
Speaking of ridiculous 40 times, Dontari Poe might've had the most mind blowing sprint of any player. Despite weighing almost 350 pounds, Poe ran the 40 in under five seconds and bench pressed 225 pounds 44 times (!) in '12. Poe was so impressive Barack Obama even referenced him in an interview.

7. Deion Sanders
No combine list is complete without Prime Time. Deion Sanders left the 1989 scouting combine with the second-fastest 40 time of 4.2 seconds, just behind Bo Jackson. Sanders was later drafted fifth overall by the Atlanta Falcons.

8. Julio Jones
Julio Jones had one of the best workouts of any wide receiver during the 2011 combine. He ran the third fastest 40 and posted the best long jump of any wide out. All with a broken bone in his foot. What a freak!

9. Tony Mandarich
Tony Mandarich highlights a cautionary tale for scouts at the combine. Mandarich benched 225 pounds 39 times, while running a 4.65 40-yard dash at over 300 pounds in '89. His measurables, however, did not translate to the pros.

10. Matt Jones
Described as a "freak" at the 2005 combine, Matt Jones was a converted wide receiver after playing QB at Arkansas. The 6-6 wideout ran the 40 in 4.37 seconds, but he was never able to make an impact in the NFL.

11. Stephen Paea
At the 2011 combine, Stephen Paea busted out 49 bench-press reps, the highest total since 1999.

12. Vernon Gholston
The former Ohio State pass rusher dominated the 2008 combine with the most bench reps of any player. Gholston was drafted by the Jets and is widely regarded as a huge bust.

13. Robert Griffin III
Quarterbacks usually don't post times like RG3 did at the combine. Griffin recorded the fastest 40 since Michael Vick in 2001 with a 4.41.
14. Tavon Austin
At the 2013 combine, Austin's small stature didn't stop him from being a freak. The former receiver from West Virginia ran a 4.3 40-yard dash and had a 32-inch vertical jump.

15. J.J. Watt
Watt, a former walk-on at the University of Wisconsin, was a top performer in almost every category at the combine in 2011. Watt seemed to turn into a pretty good player, huh?
