Raiders boasts arguably the greatest athlete in sports history at running back. That athlete is the multi-sport star Bo Jackson. He reportedly ran a 4.12 40-yard dash at the NFL Combine. He was chosen by the Buccaneers in with first overall pick in the 1986 draft but chose to try his baseball career. The Raider would then get a steal in Jackson in the next draft when they nabbed him in the seventh round. He averaged 5.4 yards per carry over four seasons in the NFL, culminating in a Pro Bowl nod in 1990. But a severe hip dislocation would cut his football career short.

Five years later they drafted Napoleon Kaufman who reportedly ran a 4.31 40 yard dash. Kaufman played for the Raiders for six seasons and stands among the team's all time leading rushers.

In 2003, the team drafted Justin Fargas who is tied for the best broad jump in combine history at 11'5".

Darren McFadden is the current combine standout for the Raiders. He ran a 4.33 40 yard dash which was the second best time by a running back in the last decade behind only combine record holder Chris Johnson. McFadden also tied for 4th among running backs in the broad jump in 2008. He was chosen with the fourth overall pick by the Raiders that year. In 2010 he became the first Raider player to reach 1000 rushing yards and 500 receiving yards since Marcus Allen in 1986. Thus far that is the closest to a full healthy season he has had in the NFL.

Outside of position drills, how important do you think these drills are in measuring a prospective NFL player?
