You might assume that if Jones left Baylor after just one season for the N.B.A., it would be a terrible disappointment to the coaches who recruited him when he was in his early teens — then had to keep in constant contact to make sure no one poached him. (Such vigilance is known as baby-sitting.) But that is not the case. If Jones leaves, it will further validate Baylor’s program and show everyone — the media, potential recruits, influential summer-league coaches who control players and sometimes broker them to colleges — that Baylor is a place that attracts top talent and produces N.B.A. millionaires. It will make it easier for coach Scott Drew to recruit more players like Jones, who then, of course, also might also leave after one season.
