When Tyson first came along, his physique made a big impact on the media - I remember all the papers being full about the size of his neck.

Also, the heavyweight era just before him was full of the Witherspoons, Tubbs etc ...... one thing Tyson did, was to change the shape of the heavyweights going forward. Big fat slobs knew they would have to start coming into the ring in some semblance of shape.
