Considering he has been hit by some of the hardest punchers in the heavyweight division. I would say he has great chin.
Superb, He Got Caught With A Peach From Smokin Bert Cooper But Rallied Back To Trouble Cooper In The Same Round. Went 24 Rounds With Lewis, Withstood Tyson, No Probs With Foreman And He Is One Of The Biggest Punchers Ever!!! Great Chin!!!
