Some friends marvel that I can enjoy college hoops so much and not give one small damn about the NBA. I've done some soul-searching on this, and come to the realization that 1) I grew up in the Kansas City area, where the hoops scene was actually improved by the departure of the Kings to Sacramento, 2) I actually grew up in Lawrence, KS, so the Jayhawks were guys I'd see walking down the street. I didn't need the NBA, really. But 3) I actually did keep up with the NBA more as a kid, because most of the great names of the day had spent some time in college, so I already knew something about them by the time they became pros.
While I was scouring rosters looking for funny names a while back, I started to notice a trend: lots of familiar names were on college rosters again. I call them Spawn of the NBA. I'd like to thank the other STF writers for helping me to track down a solid list of hoops scions.
One thing that stands out here is that the apples are falling pretty far from the tree in a lot of cases. The more transcendent the father, the more average the son, it seems. Below, we'll compare the college averages of the paterfamilias to the accrued stats of the offspring.

There's a clear flaw in this quickie examination of father/son tandems. Most of the sons are nowhere near the ends of their college careers yet. And yet, those of us who follow college hoops religously know that if either of Michael Jordan's sons had their father's potential, they would have been hotly pursued by Dad's alma mater. Jai Lucas and Larry Drew II are the most likely to follow in their fathers' footsteps at this point.

Here is a much more comprehensive list:

Austin Rivers, Doc Rivers son is in high-school now but it looks like he has serious potential.
Jeremiah Rivers at Indiana, son of Doc Rivers
Like bresq said, you can't leave out Ed Davis at UNC. And you can't leave Stephen or Seth Curry off of these lists either, even though Stephen has made his way onto the Association.
But back to Davis, his dad was an average player and he looks like he's on the path to become a superstar, much like Stephen.
Ed Davis from UNC is Terry Davis's son.
Don't forget Derek Smith and son Nolan Smith, playing for Duke.
you forgot Jordan Dumars, son of Joe Dumars

Don't sleep on Anthony Mason Jr., who's playing not for St. John's.
