Rob Gronkowski is under contract with the Patriots through 2019, but there have been rumors out- that he is considering retiring to pursue a new career elsewhere. WWE Superstar Mojo Rawley is a close friend of Gronkowski’s. At a Super Bowl party, Rawley told TMZ it was inevitable that Gronk would be in the WWE ring saying, “It’s not a matter of if, it’s a matter of when." Are we close to a Gronk debut?
