Table of contents (outline) includes three main parts. See the following scheme for better understanding:

a) Supporting detail/fact
i) Example illustrating main point I
b) Supporting detail/fact
i) Example illustrating main point I
II. MAIN POINT
a) Supporting detail/fact
i) Example illustrating main point II
b) Supporting detail/fact
i) Example illustraing main point II
III. MAIN POINT
a) Supporting detail/fact

CONCLUSION
Now, you can using comparisons as your main points and contrasts as your supporting details or facts if you'd like, or you can use a comparison as a main point, then a contrasting, then a comparison, then a contrast, etc. for the duration of the essay, supporting the appropriate details and facts as you go along.
We suggest starting out by doing the body of the outline first. Figure out what you really want to say, and then we'll figure out how to format it later. What you say is more important than how the paper looks when you are finished; think content not cosmetic.
Once you know what the main points are that you'd like to touch on, (differences in the way the field is set up, player positions, rules, etc.) then jot down a quick fact that supports that main idea (the field is set up as such-and-such, etc.) then provide an example of that (an example of this can be seen at such-and-such stadium; they have this, that, and the other). Then move on to the next point, working your way through as many main points as you need.
Leave your thesis statment until last, because you won't know what you've written about until you've written it, then bring up the rear with a conclusion, tying your thesis into your body in a nice little bundle.
