The defensive backs were the last group to participate in the 40-yard dash at the 2015 NFL Combine, wrapping up the performances in the Combine’s most popular drill Monday.
NFL Combine 2015 results: 40-yard dash times for defensive backs
The cornerbacks and safeties hit the field for the 40-yard dash Monday, and, as expected, multiple players ran sub 4.4-second 40s.

Highlighting the group of defensive backs were Washington’s Marcus Peters, Alabama’s Landon Collins and Michigan State’s Trae Waynes. But it was a different Collins who stole the show early in the morning.
LSU’s Jalen Collins is one of the biggest cornerbacks in the 2015 NFL Draft class at 6’1, 203 pounds, yet still managed to have one of the top times among the defensive backs. His 4.48 time topped most of the other participants in the drill, although it was Waynes who wound up setting the top time of 4.31 seconds. Mississippi State’s Justin Cox wasn’t far behind at 4.36 seconds, and Florida State’s Ronald Darby was right behind him with a time of 4.38 seconds. Peters managed to post a time of 4.53 seconds.
Either way, the fastest guys here were a whole lot faster than most players this year at Lucas Oil Stadium, though wide receiver J.J. Nelson ran a 4.28 and is the fastest player this year, officially.
Cornerbacks typically perform better than safeties in the 40-yard dash as a whole, and Monday wasn’t much different. Landon Collins, considered the top safety in the class by many, including SB Nation’s Dan Kadar, finished in 4.53 seconds, which was close to what was expected of the All-American.
