I think the best way to tackle this is to write the conclusion and then work backwards, expanding on the points you make in that.
To save you time, here's one I prepared earlier:
"In summary, the Adelaide 36ers do have the potential to become a major tourist drawcard.
"As outlined earlier, it will be difficult to find the $20 billion cash injection needed to:
- revitalise the basketballing operations and infrastructure in SA;
- build a 30,000 seat mega-stadium in the Adelaide CBD;
- recruit a current NBA superstar to play for the team and serve as the team's public face.
"However, should this be done, I am confident the team will become a local, national and international drawcard. As a highly respected basketball authority has noted, there's no 'I' in "team", but there's plenty in "winning" and "individualistic" (Hamburger, B; 2005)."
Feel free to plagiarise any or all of this, and standby for the big fat A plus.
