The idea of remembering the audience looms large in a speech like this. The teammates on a soccer team endured a great deal of struggle and sacrifice. This needs to be included in a speech to the soccer team. Recalling difficult drills and skills in practice would be a part of this. Perhaps, reminiscing over a particularly grueling technique, like the slide tackle, or even recalling a time of pain in running sprints would be good here. These moments' difficulties can be recalled in a speech, transforming a moment of intense pain into one where there is a collectivity and solidarity. Additionally, I think that it might be important to include a point to address how there were different points when individuals wished to quit, but remaining together enabled the team to be the collective unit it is today. Something here about how sacrifice enabled everyone to become better would be appropriate. If your soccer team was successful, it might be good to pivot from this point into the idea that such sacrifice resulted in success. If your soccer team did not see wins and losses translate, I would suggest that the speech invoke the idea that the lessons learned transcended mere wins and losses. Perhaps, this would be a nice ending to the speech as it helps to bring out how the value of team is something that is beyond the results, worthy of fighting and sustaining sacrifice for belief in one another.
