When you're searching for recruits, you need to keep your projected level set at D-II. If the recruit doesn't show up in the D-II search, he will not sign with you.
Vision means the number of recruits that show up in your D-II search. The more games your team wins over the past 3 seasons, the more of the better recruits will show up in your D-II search. So right now your main goal is to win as many games as possible. If you win 10 or more games this season, you should be able to see more high quality recruits in your recruit search next season. The more wins, the better.
