how would you deal with offering say 3 WR and only having 1 spot? Would it be acceptable to say 'first to commit gets the spot' and then the 6 month commitment would disappear? Surely you can't mean that you can only offer your top target at each position, or the number of that position you plan on taking?
Then you get the issue of the 'Athlete' getting called whatever position fits the needs of the team. By this system you couldn't really have more than your allotted scholarships made as official offers or you would further risk over-signing. The other side of this is 'sign now or we'll offer your spot to someone else.' It becomes a pressure thing since the recruits would know that the school CAN'T revoke a scholarship to another player if they sign first.
Decent concept, but lots holes.
