Over the weekend Rob Gronkowski teased another big announcement.  The last time he teased a big announcement it was to announce a partnership with a CBD company.

This time around Gronk has added to speculation that he’s coming back with some recent posts on Facebook.  One of the posts is a repost of a Tom Brady video from 2016.

In the video Brady uses a conch shell to call his receivers.  Gronk added the caption, “Tom Brady, do you think this thing still works?!!”
