In front of approximately 30 NFL teams ― including some members of the Chiefs’ staff, according to Northern Illinois football spokeswoman Donna Turner ― the 5-foot-11, 193-pound Ward proceeded to record a 38-inch vertical jump, a 10 1/2-foot broad jump and, most importantly, a 4.45 40-yard dash.

When adjusting that 4.45 to the combine numbers, I wouldn't go any higher than 4.52, and those are explosive numbers in the vert and broad. Most importantly, Ward's athleticism shows on tape - and often - because he's an instinctive, cerebral player who puts himself in positions to make plays. I figured he'd run around a 4.50 (which is what I'd adjust the 4.45 to).
4:45 – 1st & 10, -> 49 YL: Lined up five yards off the outside shoulder of the LT. Offense in Wildcat formation. Hand off to RB, pitched to QB coming from the WR position. The entire defense bites on the handoff. When the QB receives the pitch, Jimmie Ward is standing at the à 44 YL. The QB throws to a receiver at the à 2 YL, and Jimmie Ward breaks up the play. Amazing recovery. For anyone questioning his make-up speed, give this play a look. QB was late on the throw, but a beautiful play by Ward. Two teammates have a head start on him but finish a good three yards away from the play.
