I get the attraction of playing vs UNC/Duke on national TV...it must be awesome as a player and a parent. But it has absolutely no impact on the NBA. In today's NBA, they will find you and dissect you to the nth degree regardless of where you are playing. I would argue that it's far easier for Danny Ainge to pop in on a Tuesday night in Storrs than in Syracuse.
Unless you are a lottery pick, the real money to be made in the NBA is your second contract -- that's where you set yourself up for life. If I was KO & Company, I'd be telling Dad that while playing in Raleigh a couple times might be really cool, what is actually amazing is the thought that your grandkids may never have to work a day in their lives. And if you focus on this as the real goal here, then you should be prioritizing coaching, and especially learning how to be a plus defender -- because that's how your son will reach his 2nd and 3rd NBA contracts.
