How about an essay on the "Styles makes Fights" analogy?
You can discuss that the true art of the Sweet Science is hitting without being hit.
Furthermore, you can discuss various styles of fighting that emphasize such and elaborate on the differences of styles (i.e brawler verse a pure boxer).
If you can use visuals such a videos use specific fights with particular boxers that exemplify those styles.
Example: Two blood and guts brawlers: Gatti/Ward I
Two counter punchers : Floyd/Marquez
One boxer one brawler: Ali/Frazier I
Understand these are just random examples hope this helps you in the right direction.
