Weatherspoon made all the defensive calls during the Cardinals' first OTA on Tuesday, Mike Jurecki of FOX Sports 910 Phoenix reports. Weatherspoon's injury-laden career culminated in a torn Achilles last June, which erased the entire 2014 campaign, but shortly after signing a one-year contract with the Cardinals in March, he relayed that the most recent ailment was "completely healed." In the previous two offseasons, Cardinals general manager Steve Keim inked Karlos Dansby and Antonio Cromartie to such prove-it deals, which they were able to parlay into significant paydays after productive seasons. Only 27 years old and a 2010 first-round pick, Weatherspoon's background indicates that his best years could be in front of him, if he avoids the injury bug.
