Wilder sparred Wlad but never called him out after. Why? Wlad slapped him around in sparring, same as Haye did.
Wlad is 40 year old inactive, and out of his physical prime as his bulk sapped his speed.....
He'd still beat Parker and Wilder.
He could beat Joshua but would lose to Wilder and Fury.....
Wlad simply have trouble with facing people bigger than him
