To almost guarantee getting this achievement, when you choose your position at the start of your career, choose to play as a Small Forward (SF).
No matter where you end up being drafted, at the end of your first season you will have a contract offer from the Orlando Magic (unless you were drafted by Orlando some how). In this version of NBA 2K, they do not have an actual SF so they will 100% be interested in your player.
They also offer 425+ points per game minimum whether you foul you're way through high school, college, and/or your first NBA season or play them out legitimately.
As they don't have any SF on their roster, you should be starting the first game of the season and never look back from there.
It will unlock either before or after the opening tip off.
