Celtics forward Grant Williams has a ton of interests off the court, and one of those interests is comic books. He even calls himself Batman.
Last year, Williams assigned nicknames from the Marvel universe to everyone on his team. Jaylen Brown was Black Panther. Tatum was Vision. Robert Williams was Thor. Marcus Smart was The Incredible Hulk. Payton Pritchard was Quicksilver. His coach, Ime Udoka, was Nick Fury.
