Who Ran the Fastest 40-yard Dash at the Combine?

Without question, the marquee event at the Scouting Combine each year is the 40-yard dash. 

Just ask Adidas, which promised $100,000 for the three fastest times by players who signed with the company.

To see which prospects may have helped their draft stock based on their respective 40-yard times, we compiled the top times for each position as well as the best overall.
