because, if you recruit a season after finding out all the highest ratings, you will see that the top tier schools magically know what players are actually rated. Say Bama, right now I have the list of players that are the best at their positions, Bama is currently recruiting 12 players, and has a full list. 18 of the top 25 top players are magically on their recruiting list, even though there are higher rated recruits at some of the positions. USCe which is currently a star behind them, and at least a level down, has filled up with players around the 5-7 best at their position.
Now, this changes some depending on if players are bad fits, but doing it the way I do it actually evens out recruiting some because of this advantage. The CPU schools seem to recruit based off of the actual player ratings to an extent, before they even recruit them.
