IMO, you guys all are making this too complicated.
It doesn't matter if the offer came from school choice, 1,2 or 3. mattm is an 09 who has gotten an offer from a school that is interested in him, at this time in the recruiting timeline, the other schools most likely have or have not shown an interest but may or may not later on. They may not be interested now, he has his whole spring and next summer to spark that interest and let them know he is interested in their program.
Calling or emailing a school now that has shown little or no interest is only going to give you one answer we will watch you, and they most likely couldn't care less what he was offered now. Coaches do not like to be backed up against the wall, nor so they like feeling that you are playing the more money game with them. They may do it if you are considered a top HS prospect. Obviously being in a building stage they have more money AT this time to offer.
mattm, if it doesn't feel right then don't worry, you have plenty of time. If it has everything you are looking for, including academics, that's important, only you can decide. IMO.
Remember it is only an offer, be up front and honest that you are not ready to committ. You will not sign you NLI until next November.
If you are ready, then go ahead, if not don't. JMO.
