PLZ HELP! NO ONE IS HELPING ME :( How does the author contrast the two boxer’s styles?

Here is the text!

While some youngsters were into street negatives, Antonio and Felix slept, ate, rapped, and dreamt positive. Between them, they had a collection of Fight magazines second to none, plus a scrapbook filled with torn tickets to every boxing match they had ever attended, and some clippings of their own. If asked a question about any given fighter, they would immediately zip out from their memory banks divisions, weights, records of fights, knockouts, technical knockouts, and draws or losses.

Each had fought many bouts representing their community and had won two gold-plated medals plus a silver and bronze medallion. B The difference was in their style. Antonio’s lean form and long reach made him the better boxer, while Felix’s short and muscular frame made him the better slugger. Whenever they had met in the ring for sparring sessions, 2 it had always been hot and heavy. Now, after a series of elimination bouts, they had been informed that they were to meet each other in the division finals that were scheduled for the seventh of August, two weeks away— the winner to represent the Boys’ Club in the Golden Gloves Championship Tournament.
