Rob Gronkowski was in full Gronk mode during an appearance on “FOX NFL Sunday” when he threw major shade at tight end Jason Witten while discussing the Cowboys struggles.

Gronk, who is one of the greatest tight ends of all-time, blamed the Cowboys veteran tight end for not making plays in the red zone.  The former Patriot said during his rant that the Cowboys, “could use a tight end like myself.”

This all-time performance comes after Gronk teased another big announcement.  Patriots fans are hoping he’s announcing his return.
