One call (either player or coach) to see if you are a backup. If so then, scouting trips only. Start with 5, then another 5, then another 5, etc. Obviously you would want to focus this on close players. How many will be partially determined by other interest he is getting. If you are not the only one trying to pull down (or a team from his level is pursuing) he won't drop easily. Usually will drop after 10. Had one that took over 20.
