Tony Gonzalez took to Instagram to show he is working out and after the news about Rob Gronkowski coming back; Tony is ready to make a comeback of his own. Tony is excited about the thought of two tight end sets with Travis Kelce, Sammy Watkins, Tyreek Hill, and Patrick Mahomes. Obviously, this is a joke that he’s just having a little fun with, but could Tony Gonzalez actually make a comeback if he really wanted to?
