Not necessarily.
PG is basing its events on players' draft years, which of course is also the year that college recruiters are looking at.
But you cannot get to the end of the recruiting road without someone noticing your son's age. If he is standing out because he is "a man among boys", that is not really to his advantage if he's just further along in physical development than the other guys on the field. Sooner or later his DOB will factor into the extent to which people view him as "projectable" vs. already at or close to his ceiling in terms of physical development.
I would suggest your son play with his age group at least until the summer after his junior year, so that both you and he can get a more realistic view of where he truly measures up against his peers. Otherwise you are apt to get an overly inflated impression of his capabilities, which can lead you astray when you start setting your recruiting goals.
