If you have a 6-star prestige school coming off a successful season, you get almost too much interest in your school and it becomes VERY easy to cherry pick the top recruits. You sort of have to limit yourself by setting some rules and boundaries as to who you can pursue and who you can't.
I remember a couple years ago, some guy came out with a set of guidelines, saying you could go after any in-state recruit, a maximum of like 7 players from the big 3 (California, Texas, Florida) and so on and so forth. It was pretty cool and made recruiting much more challenging.
The thing is, if you just take what the game allows, you can build a super team, like the guy above, and you just keep fueling the fire. Your team becomes more dominant and it gets easier to nab recruits.
