Arizona Cardinals cornerback Antonio Cromartie posted an Instagram video and captions where he refuted losing any of his trademark speed.

The former New York Jets cornerback says he ran a 4.34 and a 4.36 in the 40-yard dash.

 "And (people) say I've lost a step," Cromartie wrote. "Only thing I can do laugh at you all. Ran 4.34 and 4.36 in the 40 today after a workout and I'm only getting faster."

Whether Cromartie has lost his speed doesn't appear to be an issue.

Whether he remains an inconsistent player is a more relevant question.
