The NFL opened up their tampering period on Tuesday at 10am in Arizona. What that means is that they can negotiate with free agents, but nothing can become official until Thursday at 2pm Arizona time.
Unless that something is re-signing your own players, like Jermaine Gresham, or bringing guys back on tenders like Zac Dysert and John Wetzel.
Get the information as you need it here though.
With teams now actively chasing down free agents, longtime Cardinals pass rusher Calais Campbell is drawing interest from an unexpected club in the AFC, the Jaguars, per Ian Rapoport.
