Per The Athletic's Jay King, Tatum used his offseason growth spurt as a point of comparison with the Milwaukee Bucks star.
"I tell everybody I've got the same genes as Giannis," he said. "I'm still growing. Like, three more inches and 30 more pounds."
King noted Tatum has grown three-quarters of an inch since being drafted in 2017 and is now 6'7⅝" but will be rounded up to 6'8" on the Celtics' official roster.
