Just saying too wrote:
AJ Nation, Nicole Blood, Lauryne Chetelet, Christine Babcock, Christy Adamack, Annie St.Geme, Marie Lawrence, Ben Sitler, Michael Coe, Alex Dunne, Chad Hall, and a few other Californians I can name here, never lived up to thier superstar high school potential. Some never ran a college race! (Ok Marie is from Nevada!)
I'd disagree with you on AJ, Blood, Lawrence, Coe. All of them lived up to their potential in college compared to most other HS runners. AJ has gone 3:36 and is still at it, blood 4:14, 9:08, 15:38, Lawrence 9:40 in the steeple, and Coe 3:56/7:48i. Most HS stars don't become olympians or run world beater times. All four of them ran times that were are respectable and showed improvement over HS by a good amount and many HS runners as you note don't do anything in college, some never PR again, or if they do it's very small and you never hear about them. So i don't really think those 4 are good examples.
