Like what ggallagh said if the email says you're a back up option or the like, they can be pulled down with 10 evals at the D3 level. Sometimes if a player is within 70 miles they will just let you recruit them like as if they were at the D3 level, accept visits. Sometimes you'll hear don't call me again or something similar, or don't return your call and your wasting your money on them.
