Dallas Cowboys QB Dak Prescott has yet to sign his exclusive franchise tag and has not been participating in the team’s virtual offseason workout program. But head coach Mike McCarthy says he has little concern about Prescott. ‘He’s involved in a business situation and I have full confidence that he’ll be ready to go,’ McCarthy said on a recent media conference call. ‘… There has been communication. I mean this is the way these business situations go sometimes. You respect that. I have all the confidence it will work out.’
