I think that you can structure this in an elemental manner. Much of this is going to be dependent on what has to be done with it in terms of the requirements of the assignment. In assessing this, I think that you will be able to figure out how the essay should progress. Naturally, I believe that you are going to have to make very clear the idea that both sports are similar in skill sets. Both require coordination, extreme level of practice and repetition, and both involve the success of one merging with the success of others. I think that being able to specifically identify how each sport represents these conditions and then contrasting it with the levels of difference in both might be a good idea. I think that you can find levels of difference in the specificity of refining skills in both and how training programs in both differ.
