Calvin recorded a 4.32 time in the 40-yard dash under rainy conditions on a soggy Witter Field. His consensus 4.32 was faster than any player at this year's NFL combine. The last time a wide receiver was under 4.32 at the combine was the 4.28 recorded by Jacoby Ford of Clemson in 2010. Ford was drafted by the Oakland Raiders in the fourth round of the 2010 NFL Draft.
Calvin added two impressive marks in the broad jump (11'1") and vertical jump (40.5") that would have tied for the best and tied for fourth-best at this year's combine, respectively.
