Impending free-agent WR Randall Cobb (Cowboys) is scheduled to become a free agent for the second consecutive offseason, but the presence of new Dallas Cowboys head coach Mike McCarthy – who worked with Cobb over the first eight seasons of his pro career with the Green Bay Packers – may play a role in his re-signing with the Dallas Cowboys.’When it comes to free agency, you never know how it’s going to play out. But it could (have an impact). You factor in all the different pros and cons to whoever’s offering and who wants you, and you find out where you’re valued, and how much you’re valued,’ Cobb told USA TODAY’s Doug Farrer.
