Looks like the fourth and final session starts tomorrow . Some coaches at all four (most) wait until the end to start processing. Though a TRUE RECRUIT could be contacted soon after the event ended. This does not prohibit your son from e-mailing. As others alluded to, which schools were contacted PRIOR to the event?. These are definitely ones you want to follow-up with. You wanted to be on their clipboard "watch list". Agree with others not to let other offers slide. So what you really want to find out is where your son is "on the board" of the schools your son would select over the schools which offered. Schools should be able to tell him at this time. All schools aren't on the same timeline.That's what makes things difficult, Good luck! Thanks for posting.
