One-and-done: I do not like the option, but . . .

Since the NBA evidently is not going to change its rules, there is one thing that the college game could do to help fix the problem. Just go back to making freshmen ineligible. Then, those big money one-year sorts would be sitting out their freshmen years, so all of them would probably go to the NBA out of high school. Not a very good option, but it might send a message to the NBA.
