I hear Flo and Dorian screaming from the crowds, I see the rest of them team waving their Trinidad flags high in the air, I look back and see my coach, as ready for the fight as I am; this was the moment I realized that this is an individual sport but doing it alone is impossible.
This part is a run on sentence... it is complicated and hard to identify as a proper sentence or an improper one.. but really... you should simplify. And to be honest, I think you should not give all these details, like their names and the "looking back to see the coach..as ready as you are..." It is important for you to know what impression or message you want to send to the reader. What is that impression? In what way will the reader's life be better for having read this essay?
Whatever your gift is to the reader, you need to really know it. That way, you can trim away extra details that distract attention away from the experience you want to provide.
I see this as your theme: doing it alone is impossible.
And this expresses the theme, too, but it DEFINITELY needs to be simplified: teamwork is probably the most valuable lesson a person could learn and that the best friends (are the ones that are those that are??) with you ...
The theme, then, is a good one, but it needs to be developed more. The point of the essay is to give the reader a NEW insight. What new insight, related to supportive friendship and teamwork, can you share with the reader?
