Georgia Southern running back Jerick McKinnon's 4.41 was the day's No. 2 time in Indianapolis, and Archer did eclipse the 4.27 run by Buffalo Bills receiver Marquise Goodwin at the 2013 NFL Combine.
The burst of speed adds to the intrigue surrounding Archer ahead of the NFL Draft this spring. As a Kent State junior, Archer garnered attention as an all-around threat with 1,429 rushing yards -- 9 yards per carry -- as well an average of more than 14 yards per catch and three kickoff returns for touchdowns.
His numbers were not as gaudy during an injury-marred senior season, and Archer's 5-foot-8 frame gives pro scouts a built-in excuse to shy away from him.
If their concern is over durability, just remember this: NFL defenders can't hurt what they can't catch.
