Yup, I agree. Huge bonus for guys that you sign early because of the "cost savings" later. At this point, I don't see any benefit to scheduling a late visit. Either it happened because he's a new player that you added to backfill, or he's a slow mover that you can wait until your Rivalry game to seal the deal...
So, not much benefit to scheduling late, but there is the potential bonus of catching a player on an instant-sign if you schedule early, plus you reduce the risk of getting bypassed for a late visit. Early Signees and instant-signs are the Recruiting Grail in my opinion. That and guys you sign after the regular season, hidden gold mine sometimes.. I'll cover that in part 3
** edit... One factor i'm not sure about is if their is a negative impact to offering to too many recruits of a single position... ** this could impact early offers.
