Break a locked prospect

For this youre going to want to have recruiting set to Freshman, as you should for all the recruiting achievements. The best way to do this youre going to want to be at a very good school, probably while youre getting the other Dynasty achievements. Find a prospect locked to a very low ranking school. Try convincing him as much as possible with points, visits, and scholarships. If you dedicate an entire offseason (without saving, if you dont want to ruin a dynasty year) to 10-15 of these recruits you should have no problem getting one single recruit.

If you're really struggling, Sim a season with a good team like Alabama, and make sure cpu assists are set to on. After a few tries you should unlock the achievement.
