It's all about your prestige rating. I landed my first ever 4 star recruit at Tulane this past year in GG with a 48 prestige, and he was my email guy. When you're working in the 30's, 2 stars will really be the best you can get; in the low to mid 40's, 3's, once you hit 50's you start getting the shots at some of the better players available.
The nice thing is that the teams you're playing on a regular basis will be recruiting players in the same range as you are.
