Could Stipe Miocic Be UFC's 'Next Great Heavyweight'?

"I believe that guy could take it all the way. I really do," said trainer Trevor Wittman, who worked with Miocic during the fighter's visit to the Grudge Training Center in Denver recently. "He's the next great heavyweight coming into the UFC. His composure, his attitude, his willingness to learn and be open to things, his toughness -- it's just all there."
