I signed a player with a scouting trip and a scholarship a couple seasons ago.
This is one of those things that depends upon the player. Some guys will sign for lower amounts than others.
I've had guys who (as far as I know) have never considered anyone and a scholarship and a home visit won't get them to consider me (and a home visit is more valuable than a scouting trip).
On the opposite end, there are of course the guys who beg you to consider them and put five colleges on their considering list for no reason, LOL.
