I concure...if you trying to fill your roster with 5 star players all the time good luck. If you don't have a spot to fill, or your trying to simply imporve over what you've got...it'll be hard to get the 5 star recruits.
I leave some three stars hanging (if i'm using a 6 star prestige team). At times i've had guys sign that i didn't fully recruit, simply gave points the first week, then went right back and removed the points. I still got a recruiting report about his interests, but never actually recruited him at the end of the week, or at least it didn't seem to take away recruiting points for what i've been calling "pseudo scouting." or "scout" them for the 3-6 recruiting points...that can keep some interested.
Another key i find that i'm not sure if people are using as a tool...if you browse the lsit of position and ATH, sometimes you'll see a red arrow. This doesn't mean he doesn't want to come to your school...the exact oppposite. I throw a few points at them and watch my school climb back into their radar for schools. They started loosing interest since you didn't recruit them. They are typically guys who didn't have your school in the top 5 choices...but would still consider coming to your school for a shcolarship.
