The 2015 NFL Draft Combine is underway. Saturday will feature one of the most anticipated drills at the event: the 40-yard dash for wide receivers. While it's always fun to see offensive linemen run the 40-yard dash and receivers do the bench press, the 40-yard dash is possibly more important for receivers than any other position. This is where players can seriously make a difference to scouts.
Alabama's Amari Cooper started the day off in impressive fashion. Cooper made a reputation for himself as one of the best route runners in the country under Nick Saban. Now he showed that he can do all that with 4.43 speed:
Dorial Green-Beckham is bound to be one of the draft's most intriguing prospects. The wide receiver was dismissed from Missouri, but enters the draft with great size. He proved he's pretty fast, too.
Dorial Green-Beckham (6-5, 237) runs unofficial 4.50. Similar size to Calvin Johnson but not quite the 4.35 (handheld) that Calvin ran in 07

The fastest unofficial 40 time of the day went to Alabama-Birmingham's J.J. Nelson, as he managed to put up a 4.29.
