Also, what about the follow on questions – if he EDed at the 1st school, presumably he loves it. Does he love the 2nd school as much, leaving sports out of it?
Can he play his sport at the 1st school?
Finally, it’s really late in the recruiting cycle – will your son get playing time at all, assuming due to the timing that he’s not an impact player? (On my son’s college soccer team every year there are recruited kids that get zero playing time. Some years there are cuts, to recruits).
Answering those questions may make him more comfortable with his decision.
