Here is a case of the 8th best player coming out of HS and drafted in the first round turning down the money...

Obviously, they don't publish the scholarships that players receive. Based on his stats on place in the rotation, I am only assuming that he is not on full ride. So, your example is lost on me.
However, UFbaseball has 0 international Players and 28/32 players are in state. UCLAs roster is of similar proportions so I guess that could boost your argument somehow. Still, you need to do the math. 4.5 for an 8-9 player roster in tennis has better odds of players getting money than 11.7 for a 32-35 player roster.
It's funny to me that people in this country complain about kids not getting athletic scholarships. No other country in the world even has a system close to ours that allows a kid to get significant athletic scholarship money. Here in America, we just complain that it isn't enough or that the "right" people aren't getting the scholarships. We have it pretty good.
